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?

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

and it give the error like this:

could someone give me some advice?

Thank you very much!
