combined DynamicMotion and DynamicRefinement ?

lbordier · August 31, 2011, 03:58

Hello,

I'm trying to use dynamicMotionFvMesh and dynamicRefineFvMesh.

If I undserstand well, the refinement settings have to be written in the dynamicMeshDict in a same way than the mesh motion properties.

My problem is that, if I want to have the mesh displacement I have to write in the dynamicMeshDict :

Code:

dynamicFvMesh    dynamicMotionSolverFvMesh;

... followed by the dynamic motion options

But if I want to use dynamic remeshing, I have to write in the dynamicMeshDict :

Code:

dynamicFvMesh    dynamicRefineFvMesh;

... followed by the dynamic refinement options

Writting the two former settings in the same dynamicMeshDict seems not to work, only the dynamic motion seems to be performed.

How can I have the two of them working together (if possible) ?

Thanks.

Not my speciality (so someone might prove me wrong) but I'm afraid you'll have to write a dynamicFvMesh that combines both of them (I guess by inheriting from dynamicRefineFvMesh and transplanting the dynamicMotionSolverFvMesh-functionality, but that is only a guess)

Are you able to solve the problem?

If you solve the problem, Can you tell me, how you solve that problem? By editing library file?
TIA
