How to use multipoint tutorial file for DARhoSimpleCFoam?

[usmanshahid90]

I am interested to perform multipoint optimization for subsonic, transonic and supersonic flight conditions at different altitudes.
Multipoint tutorial use DASimpleFoam, which is incompressible. Kindly help me in this regard.

We currently do not support switching solvers during optimization. For your case, I suggest you try DARhoSimpleCFoam. It is mainly for transonic and (weak) supersonic cases, but it may also work for subsonic conditions. You need to use the DASimpleFoam tutorial as reference and change flight conditions and the solverName to DARhoSimpleCFoam. Again, I suggest you go over other single-point optimization tutorials before trying the multipoint one.

@wndzjl If you want to use different solvers in an optimization, you should take a look at the NACA0012/multi_case tutorial.

Does this work with version v2 code? That is, do not use openmdao

[friedenhe]

Nope. It works for v3+ only

[wndzjl]

Sorry, I meant if it can be used with code types like runScript_v2.py instead of runScript.py. That is, do not use openmdao.api, mphys.multipoint, dafoam.mphys, mphys.scenario_aerodynamic libraries, etc. Because this version is a little hard to understand.

Nope, the multicase is available for v3 scripts only
