Problem with dynamicMesh
 

Hi all,
I'm trying to simulate the mesh motion using movingDynamicMesh with displacementLaplacian solver.
The initial mesh is created with snappyHexMesh and the motion is prescribed to the different patches through pointDisplacement file in the /0 folder. I noticed that if I don't change the polyMesh in the /costant folder (that in default store the blockMesh) with the one produced from snappyHexMesh (coping the folder), the dynamicMesh solver starts to move from the blockMesh mesh.
Is there any method to store the polyMesh of snappyHexMesh in the costant folder?

I'm sorry for the question, but I'm a very new user.

Thanks

Dario
