OpenFOAM Executables (Binaries)

  • The OpenFOAM binary executables are located in the path $WM_PROJECT_DIR/platforms
  • You can jump to the OpenFOAM platforms directory e.g using system variable $WM_PROJECT_DIR/platforms:
    # cd $WM_PROJECT_DIR/platforms
  • This directory contains the binaries generated when compiling the applications directory (after compilation the binaries will be located in the directory e.g.:
    $WM_PROJECT_DIR/platforms/linux64GccDPOpt/bin) and the libraries generated by compiling the source code in the src directory (after compilation, the libraries will be located in the directory $WM_PROJECT_DIR/platforms/ linux64GccDPOpt/lib).
  • If you have installed OpenFOAM following the default instructions, you compiled the 64-bit version, using the gcc compiler, with double precision, and optimized version. This is reflected in the name of the directory linux64GccDPOpt.
  • OpenFOAM 32-bit is also possible to compile. The simulation is nearly two times faster. One has to be very careful about the results. Some cases results are same as 64-bit, but some cases are different or even totally wrong.

Watertight property

Watertight property of the input STL geometry is extremely important for meshing process. The computational mesh is created and bounded by the STLs. Any hole inside, usually at edges of neighboring parts, may cause a crash of a meshing process. It is sometimes referred to the watertight property as point-to-point correspondence of vertices. The property is visualized in Figures below.

INPUT RULE 6: Each component has to be water tight.
