Using TCR within I-Simpa

TCR is already embedded in I-Simpa. Follow the next instructions to run a calculation with the TCR code in I-Simpa.

Double left click on the TCR calculation code in I-Simpa to display all calculation parameters:

Meshing

Some calculation codes may require a meshing of the domain (SPPS for example). I-Simpa used the TetGen meshing code (A Quality Tetrahedral Mesh Generator and a 3D Delaunay Triangulator). See the documentation for more information.

Within I-Simpa, TetGen can be paramatrized:

  • “Test mesh topology”

    Check/uncheck for activate the debug mode of TetGen (debug mode).

    Avertissement

    With the debug mode, the meshing is not realized.

  • “Additional parameters”

    Add parameters to the TetGen default parameters.

  • “Radius/Edge ratio”

    Defines the ratio between the radius of the sphere that would contain a mesh and the lenght of the mesh. This parameter could be useful in order to avoid long meshes.

  • “Scene correction before meshing”

    Check/uncheck for trying to repair the 3D scene if possible.

  • “User-defined paramters”

    Defines new parameters by replacing default parameters.

  • “Surface receiver constraint”.

    Check/uncheck for using a given value of the mesh surface “Surface receiver constraint (m²)”.

  • “Surface receiver constraint (m²)”

    Maximun accepted value of the mesh surface (m²) for a surface receiver. The value can be modified only if the “Surface receiver constraint” parameter is checked.

  • “Volume constraint”

    Check/uncheck for using a given maximum value of the mesh volume “Volume constraint (m3)”.

  • “Volume constraint (m3)”

    Maximun accepted value of a mesh volume (m3). The value can be modified only if the “Volume constraint” parameter is checked.

TCR Calculation parameters

  • “Active calculation of atmospheric absorption”

    Enables calculation of atmospheric absorption.

  • “Export surface receivers for each frequency band”

    Check to export the surface receiver results, for each frequency band. If uncheck, only the global value is exported.
