dynamic mesh doesn'r refine

Elham · February 8, 2016, 21:57

Hi everyone,

I am using interDyMFoam for modelling a droplet falling. for coarse meshes dynamic mesh works. I mean it can refine mesh around the droplet and the refined mesh moves with the droplet. But for refiner meshes it doesn't work and I can't see any changes in mesh when the droplet is falling. I have tried to change the dynamicMeshDict parameters but still couldn't find any solution.

Thanks for any help.

You provide no information at all for others to be able to help you.
Post your dynamicMeshDict and pictures of your falling droplet with the mesh at different timesteps.

Thanks TobM for your comment. I have attached my DynamicMeshDict and blockMeshDic as well as 0 second and 1 second pictures of the falling. The red area is the water droplet.
Thanks for your comments.

You have a mesh with 1.000.000 cells and as maxCells in your dynamicMeshDict 240.000.
That can't work, when maxCells is reached no mesh refinement is done.

It was so silly that I didn't pay attention

. Thanks a million.
