question about icoDyMFoam
 
This question trouble me for a long time:
In piso loop we need to slove pressure poisson equation

{...
fvScalarMatrix pEqn( fvm::Laplacian(rAU,p)== fvc::div(phi) )
...
...
solve(pEqn)
}

I think the phi should be relative phi if mesh is moving ,but in icoDyMFoam the
phi is absolute phi when solving pressure poisson equation.Is this a bug or not ?

Hi Jinbin,

Currently there is rel/abs flux correction in the OpenFOAM-2.3.x pimpleDyMFoam solvers. I'm not sure which version of icoDyMFoam you are looking at but inspecting the pimpleDyMFoam source code might answer your question.

Cheers,
Kyle
