Report builder windowThe report builder enables you to create a fully customized report. You can select the parts you need for your report from a variety of predefined report modules. The report builder consists of a table with 2 columns and a button to initiate report generation. The first column shows the report modules and the second column displays the availability of the module. To select a report module for inclusion into the report to generate, simply check the check box next to it. The report modules are grouped according to the frequency they are printed together in one report. If you check/uncheck a report module group, all modules will get checked/unchecked. The availability of a module depends on several factors: A report module may not be available, because the current model doesn't contain the features the report relies on. E.g., if your model doesn't contain power sources, the power sources report won't be available. The availability of some report modules also depends on the state of calculation execution. If you didn't yet execute the thermal coefficients calculation, the respective report won't be available. Finally, if you've selected all modules according to your needs, you can generate a report by simply clicking on the button at the bottom of the form. This will open the report viewer window. Report modulesThe report modules are grouped into these groups:
Each of those groups and the entailed modules will be further explained in the subsequent sections. Model construction details reportThe model construction details group doesn't have child modules, but is a rather module by itself. This module displays all input elements of the model with the following details:
This is a fairly large report module. It can be printed in presentation or landscape layout. Remark: Data of vapour diffusion resistance μ will be also reported if entered. Data entry reportsThe data entry report groups contains the modules
The report is used for summarizing documentation of all building components data relevant for the simulation. Compared to the model construction details report only data relevant for the calculation is reported. Resulting from the overlapping elements some materials might have no impact within calculation (being fully overlapped and thus discarded). Thus this report shall be used to document and to verify the input of spaces and power sources (boundary conditions), their names and transfer coefficients. Remark: If there are power sources included in the model (after all overlapping of elements have been resolved) their resulting (active) volumes will be calculated and output also. This values might be helpful during the entry of boundary conditions. Remark: Data of vapour diffusion resistance μ will be also reported if entered. Layered constructs and UValue calculations reportThis report lists UValues of characteristic
layered constructs at adiabatic boundaries of the model. Remark: The listing does only show UValues of layered
constructs between two spaces; Incomplete layered constructs will not be output.
The algorithm searches at all six sides of the model bounding box for adiabatic
cutoff planes (from outside towards model's interior, the first one adiabatic
plane in each such direction). If a space surface is found at first in one of
that directions, then there will be no adiabatic boundary reported in that
direction. Adiabatic planes found by that process are then intersected in pairs
at twelve edges. At these intersection lines UValue profiles are generated 
each such profile results in none, one or even many layered constructs
spacetospace. For detailed report of all data entered, including the detailed listing of all elements, please use model construction details report. Coupling coefficients reports
The Coupling Coefficients and Precision report displays the matrix L_{i,j}
of thermal coupling coefficients (L^{2D} or L^{3D} , also called heat transfer coefficients H in
some standards
or Leitwert matrix, thermal conductance matrix) and respective
precision information of the
simulation. Depending on which problems have been chosen for the Solver and on the number and type of boundary conditions following results are shown:
for the steady state (stationary) heat transport problem:
for the steady state vapour diffusion problem:
for the dynamic, transient, harmonic, periodic heat transport problem, for any period length (and eventually higher harmonics):
given as complex numbers and as amplitude/phase pairs. If the number of matrix columns output shall overrun the page width then the output of overrunning matrix columns is continued in groups one below the other. Steady state (stationary) thermal coupling coefficientsThe report displays the matrix of thermal coupling coefficients for any pair of spaces (with 6 decimal places). If N spaces are attached to the considered construction the NxN matrix will be displayed (without diagonal elements). Theoretically the matrix shall be symmetrical (i.e. L_{ij}=L_{ji}), thus the output allows precision consideration of results.
These values are used, for example, to calculate thermal bridge correction
factors  for a 3D case the "point thermal transmittance" Χ (Chi) and for a 2D
case the "linear thermal transmittance" Ψ (Psi). Remark: By multiplying the (steady state) thermal coupling coefficient L_{ij} by the difference of temperatures of respective space pairs Θ_{i}−Θ_{j} one will receive the heat stream (or the length related heat stream in 2D case) between the two spaces transmitted through the modelled component. Heat source Distribution Factors (steady state)In the event heat sources are available also, the heat distribution factors of each source to all spaces are shown too.
If N spaces are attached to the considered construction then there will be N numbers shown for every heat source in the distribution table. The ith (i = 1,N) column value of the distribution table shows the percentage of the heat provided by the particular heat source passing to the ith space. The values of the distribution table are therefore from the range 0 to 1. Because the steady state calculation does not cover the heat capacity storage, the sum of all distribution values must theoretically result in 1 (apart from minor rounding errors) allowing further precision consideration of results. Remark: By multiplying the distribution factor F_{kj} by its respective power density Φ_{k} of the heat source k and its volume V_{k} one will receive the heat stream (or the length related heat stream in 2D case) from the heat source k to the space j. (The volume of every heat source will be shown within Modelling report or Results report). Transient (instationary, dynamic), harmonic, periodic thermal coupling coefficientsProvided the solution of a dynamic, transient, harmonic, periodic problem has been computed also, the matrix of periodic harmonic coupling coefficients will be output (with output of up to 4 decimal places).
The output is provided for each requested period (period length, in decreasing
order; longest first) once as matrix
of complex numbers and additionally as matrix of norm (amplitude) and argument
(phase shift, time lag) values. Diagonal elements (contrary to the steady state case these are significant and output here) can be used for the calculation of effective heat capacities. Theoretically, as for the steady state case, the matrix shall be symmetrical, thus the output allows precision considerations of results also.
In the event heat sources are available also, the harmonic heat distribution factors of each source to all spaces are shown too. Vapour diffusion, hygric coupling coefficientsThe report will also show hygric coupling coefficients (mg/Pa*h) ("Matrix of hygric coupling") if there are results of vapour diffusion calculation available too.
Precision informationAn immediate indicator of the precision of the solutions is the matrix of thermal coupling coefficients itself  if it is not reasonably symmetrical, then further calculation might be necessary. Along with the output of coupling coefficients the necessary information about the precision of these results is output. A theoretically exact method of calculation would necessarily satisfy the condition, that the sum of heat entering a component exactly equals the sum leaving the same  for any set of basic solutions. The inherent nature of a numeric method, however, will always result in a marginal difference in the evaluated energy balance. This is referred to here as the closeup error of base solution. Dividing the closeup error by the sum of the coefficients associated with the respective base solution (space) provides a measure of the precision of calculation.
The relative closeup error shall never exceed 10^{−4} considering precise solution (see EN ISO 10211:2008). The value of the Relative CloseUp Error limit (default 10^{−4}) can be adjusted within application settings:
A warning message "(*) Warning: The precision criterion concerning the magnitude of relative closeup errors is not fulfilled" will be shown below the precision data listing if the precision criterion is not satisfied by any of base solution (the display of this message can be turned off by the application setting "Relative CloseUp Error  Warn if above"). Note: If the relative closeup error exceeds 10^{−4} (or the limit otherwise set) a continuation of calculation based on more stringent parameters for more precise solution should be considered before proceeding with further evaluation. Eventually modified (finer or coarser) raster discretisation (gridding) might be required also.
If the solution of vapour diffusion has been also computed, the associated precision information is also displayed following the results of thermal heat calculation.
Precision indicators, i.e. (*), (**) and a warning message, are shown for the vapour base solutions  based on same precision criteria (see above).
Results reportsThe Results report provides the output related to boundary conditions applied and shows results for coldest surface points of each respective space and includes their temperatures, coordinates and temperature weighting factors also. Calculation of evaluation results dependant on boundary conditions is requested by applying these values from the Boundary Conditions window. The results offered by this report are used for the assessment of fulfilling (or failing) the condensation and mould growth avoidance criteria (see EN ISO 13788). For each space the application automatically locates points of lowest surface temperature and outputs its coordinates. Also gvalues (the weighting factors) are calculated and output. Along temperatures of coldest surface points the application outputs respective dew point values (maximum noncondensing air humidity) also [1]. Respective values are calculated according to formulas of partial pressure as defined in EN ISO 13788:2002. The evaluation is executed on top of base solutions solved and superposed with respective boundary conditions (reported by the number of equations or cells solved) then further refined to the super fine solution (reported by the number of nodes evaluated). Boundary conditions and critical resultsFor each space connected to the model following results information is offered:
The temperature factor f^{*}_{Rsi} will be evaluated against the space with the lowest temperature Θ_{e} (i.e. that space will be assumed to be "exterior") and calculated according to standard by the definition f^{*}_{Rsi} = (θ^{*}_{Rsi} − θ_{e})/(θ_{i} − θ_{e}) . Remark: In a two space case temperature factors f^{*}_{Rsi} will be output in addition to temperature weighting factors g  calculated for points of lowest temperatures of surface of each space. The temperature factor f^{*}_{Rsi} can be used as construction characteristic indicator only when two boundary conditions are applied. When three or more boundary conditions (spaces, power sources) are involved then the standard requires using of temperature weighting factors g because f^{*}_{Rsi} is not suitable in such cases!.
Remark: The output of
temperature factors f^{*}_{Rsi} will be suppressed if the
application setting "f_{Rsi}  TwoSpace only evaluation"
is turned on and there are more than exactly two temperature
boundary conditions involved in the model.
If heat sources are also modelled:
Remark: The assessment of further extreme values (e.g. temperatures) at all surfaces and within interiors of all power sources is provided within the 2^{nd} part of this report too. Weighting Factors (gvalues) of coldest space pointsThe weighting factors (gvalues) will be output as a matrix for the coldest point of every space. Every column of the matrix displays gvalues for the coldest point of the space surface named in the column heading. Weighting factors g are characteristic for respective points of the construction and their value is independent from any boundary conditions. The summation of gvalues of a point multiplied by the respective boundary condition results in the temperature of that point. Under the assumption that the location of extreme poles will not change under different boundary conditions one can easily calculate the resulting temperature at these varied boundary conditions. Remark: The sum over all gvalues belonging to temperature boundary conditions at specific point (sum of values in one column without those belonging to heat sources) is always 1. Remark: If the number of matrix columns output shall overrun the page width then the output of overrunning matrix columns is continued in groups one below the other. Coordinates of coldest surface pointsThe listing of points of lowest space surface temperatures for each space shows point coordinates, the respective surface temperature, the dew point and the temperature factor f^{*}_{Rsi} also. Condensation and Mould Growth Assessment CriteriaIf requested by the application setting "f_{Rsi,min} design factors  Warn if undercut" (on by default) AnTherm will automatically evaluate the assessment of the f^{*}_{Rsi} values by comparing actual values of f^{*}_{Rsi} to their design values for condensation free and mouldgrowth free constructions (also set within application settings).
In addition, if either of the design values are undercut at any space surface there will be warning message displayed at the end of this report:
If the criteria is fulfilled on the other hand following confirmation will be printed:
Remark: The output of
temperature factors f^{*}_{Rsi} will be suppressed if the
application setting "f_{Rsi}  TwoSpace only evaluation"
is turned on and there are more than exactly two temperature
boundary conditions involved in the model. Probe Points reportThe Probe Points report us used for the output of temperatures at chosen probe points at currently applied boundary conditions .
The report outputs temperatures at points (coordinates x,y,z) defined in the window "Probe Points". For each point given the application outputs coordinates (values of x,y,z) and the value of calculated temperature. If required a trilinear interpolation is used to calculate temperature exactly at any point of the model from node values available at the super fine grid. If the chosen point is located at some space surface the respective dew point (maximum noncondensing air humidity) is calculated and output in %. If the chosen point is located outside of the boundaries of the construction only its coordinates are output. Remark: The report includes points of lowest and highest surface temperature for each space surface automatically – space name, space temperature, dew point and f^{*}_{Rsi } value (if applicable) are output – same as in Results report. Remark: The output of temperature factors f^{*}_{Rsi} will be suppressed if the application setting "f_{Rsi}  TwoSpace only evaluation" is turned on and there are more than exactly two temperature boundary conditions involved in the model. Remark: If there are power sources contained within the model this report also includes points of lowest and highest temperature within each power source (to assess overheating for example). If there is solution of vapour diffusion available also, values of saturation and partial pressure are also output at each point:
If the current value of partial pressure is higher then saturation pressure, a star (*) is shown adjacent to the partial pressure value  this shall alert on possible condensation risk at this respective point.
Remark: Shall partial solution be only available to the report (e.g. some base solution yet not calculated finally, spaces without thermal connection with the model, etc.) the respective result fields will be left empty. Please consider checking the input data or rerunning the solver and checking the output shown within the solver window in such situation.
