Dear All,
Recently, I am trying to accomplish a case. In the case, I can get the variation (delta y) for every mesh in the bottom boundary for every time step, and I want to generate a new bottom boundary by adding the variation to the old bottom boundary. But I do not know how to read the variation when adapt "dynamicFvMesh". Am I right to adapt the class "dynamicInkJetFvMesh"? Is there anybody who can give me some advice about the dynamic mesh with solution depended?
Thank you very much!
Best wishes!

Sincerely,
Detian

Dear All,
I just want to read the result in the runtime dictionary, and the .C file is like this:

could someone give me some advice?
