OpenFOAM(v2012), a fluid/continuum simulation platform, is available at SQUID.
Basic use
OpenFOAM commands can be used by reading the environment setting file with the following command.
$ module load BaseCPU
$ module load BaseApp
$ module load OpenFOAM/v2012
Please execute it by batch job. An example job script is as follows. It is an example of executing damBreak($FOAM_TUTORIALS/multiphase/interFoam/laminar/damBreak) in tutorial. Preprocessing such as blockMesh (lattice creation) and decomposePar (region division) can be done in front-end nodes. In the following example, batch processing is used. Please submit the script from the root directory of the case.
