save project's data to a project file
naming it arbitrarily.
|You will be automatically alerted to save project's data to
a file prior to simulation start to avoid any accidental data loss. If the
request to save data is always shown can be set within application settings.
Within the project's data also parameters of the
fine grid and precision setting for the solver are saved.
Solver window lets you observe the progress of the simulation
|The animation shown at the top edge of the window informs
you, that the application is currently calculating a new solution. Further
messages issued by the computational part of the application shall be
also shown in this window.
If there are
simulation results available from an earlier calculation, they will be
compared to the project data just saved. If no changes of the input are
detected the calculation step will be skipped..
|Soon after the calculation is finished the
thermal coupling coefficients and precision information for that
calculation are shown.
|The report window displays characteristic values of the
construction in the form of the matrix of thermal coupling coefficients (L2D or L3D).
The precision results shall be checked and evaluated against conformance to
standardised criteria (the relative close-up error < 10-4). If
this criteria is not satisfied the computation shall be repeated with
different parameters (of a fine grid or the solver).
Thermal coupling coefficients shown might be immediately used to assess
thermal energy performance of the construction just calculated (e.g. to
determine the Ψ (psi) or Χ (chi) values for energy rating
evaluation, energy pass or energy demand calculation).
Boundary Conditions window lists all spaces for which temperatures
(the boundary conditions) can be entered.
|Temperatures of spaces will be pre-assigned automatically:
- first space listed receives air temperature of -10°C
- all other spaces are pre-assigned the temperature of +20°C.
Spaces are shown sorted alphabetically by their names. By using some
consistent naming conventions the pre-assignment might match your
requirements in most cases:
- Exterior is listed before Interior
- Space 00 prior to Space 03 and prior to Space 10
- Room 11 is listed prior to Room 1.
If the model contains power sources (heat sources) also, they are listed
in the window to allow the entry of their power density [W/m³].
|To confirm the values of temperatures entered in the
Boundary Conditions window press the button Apply
|Boundary conditions entered are applied onto basic solutions (the g-values).
The resulting temperature distribution within the construction is calculated
as a superposition of basic solutions multiplied by the corresponding
boundary condition value.
|Actual results are calculated and displayed within
several evaluation windows.
|Results are formatted as printable textual reports which
can be also saved as Adobe PDF, MS-Word
or MS-Excel files for further processing.
The temperature distribution is available as starting point for various
Coefficients and Precision report and the
report are shown as standard reports automatically.
