Test case geometry description

  • Multi-region cases are in fact several cases connected to one case
  • Whole domain is divided into several regions and solver solves regions step-by-step
  • Most applications need a switch -region when computing multi-region cases
  • $ {\textcolor{blue}{\mathsf {In \ Linux: }}}$ Copy tutorial case multiRegionHeater:

    # cd $FOAM_RUN
    # cp -r $FOAM_TUTORIALS/\
    heatTransfer/chtMultiRegionFoam/multiRegionHeater ./

  • $ {\textcolor{red}{\mathsf {In \ Windows: }}}$ Copy tutorial case from enclosed training materials. Windows test case is different and uses #includes instead of virtual references used in Linux
    # cp -r .../CFDsupport/tutorials/multiRegionHeater $FOAM_RUN
    # cd $FOAM_RUN /multiRegionHeater
  • Test case is already preset
  • Test case is three dimensional

  • Each region has its configuration files (controlDict file is common for all regions)
  • Solver for this test case is chtMultiRegionFoam
