This is a wrapper of Star-CCM+. It can generate both volume grid and CFD solutions. User is expected to have access to Star-CCM+ executable and power-on-demand license. It is also expected that the code will be run in PBS. The following system variables are expected: LM_LICENSE_FILE (e.g. 1999@localhost) STAR_POWER_ON_DEMAND_LIC (e.g. ADeged4oUsdf6ghTln7ALP) If the user wants to generate a volume grid (runVolGrid = 1), an surface grid file must have been provided: - STLFile (a .stl file) By default, two more input files are automatically generated: - javaBatch1File: a Star-CCM+ macro (a .java file), - cshBatch1File: a C-shell script (a .csh file). However, user can choose to provide his/her own C-shell script (cshUserBatch1 = 1). If everything goes smoothly, it will generate a volume grid: - simMeshFile: the volume grid (a .sim file). Volume grid can be used to generate CFD solutions. If the user wants to generate a CFD solution (runCFD = 1), a mesh file (the simMeshFile file) must have been either generated in the previous step or provided by the user. By default, two more input files are automatically generated: - javaBatch2File: a Star-CCM+ macro (a .java file), - cshBatch2File: a C-shell script (a .csh file). However, user can choose to provide his/her own C-shell script (cshUserBatch2 = 1). If everything goes smoothly, it will generate a CFD solution: - simFlowFile: the CFD solution (a .sim file). several CSV and PNG files can be generated too. The inputs are in imperial system.
