Hello Foamers,

I am trying to use dynamic mesh to research flapping airfoil in sine pattern. I have chose the pimpleDyMFoam solver and now I have two questions.

1)I want to define a new boundaryfield of pressure in wall but I have no experience of it. Can someone give me teaching? I want to describe the equation in the new boudaryfield:



ay、w、r is changing with time, I am confused how to define it..

2)In the pointMotionU, I think the velocity of mesh should be equal to the airfoil. And I set the type of wall boundaryfield as timeVaryingUniformFixedValue. I want some guide of timeVaryingUniformFixedValue. I know it need extra files to know the velocity, but how can I give the velocity.dat?
