pimpleFoam -dict

ghastbug · March 30, 2022, 07:33

snappyHexMesh allows usage of -dict. So if I have several snappyHexMeshDict files in my case/system, I can tell openFoam which to use.
Example: snappyHexMesh -dict system/snappyHexMeshDictIChose

Is there a way to do the same with pimpleFoam?

Doesn't look like you can. You can tell it to use a different case directory, with the -case flag, but that's probably not what you are after ..

I am guessing you want to have say 2 or 3 controlDicts, each with different run parameters, and then run pimpleFoam with each one? I would do that all through scripting. i.e. either have the 3 files in your system folder, names controlDict.1, controlDict.2 etc., and then use the script to copy each one to controlDict and then run.

Alternatively just have one controlDict and do all the manipulations in the script, using the foamDictionary utility to update the parameters for each run.

Hope that helps.
