Running 3D Adaptive mesh in parallel *interDyMFoam*

Howdy Foamers,

So I am currently trying the adaptive mesh capabilities in interDyMFoam. So far,
I have met with what it could be an issue. The problem is that every time I run my
case (a spillway) in parallel, the dynamicRefinefvMesh seems to refine only regions
close to the boundaries, instead of all of the interface (bounds: alpha1 [0.01,0.99]).
It seems that the dynamicRefinefvMesh class only works in serial (or, at least the
tutorial cases work) but I cannot afford to run my case in serial.

In short, what I want to know is if the adaptive refinement only works in serial. If
not true, what I might be doing wrong.

any help is kindly appreciated,

Santiago

hello,

Adaptive refinement work in parallel.
Take a look at your dynamicMeshDict file. There check your maxCells value. If maxCells is too low, this will stop the adaptive refinement.

Hi Olivier,

I put a value of 20e6 for maxCells, and still is not refining. (I am using OF 2.2.2).
Do not know what is going wrong.

thanks,
