Hello, everyone

I have a question about the pimpleDyMFoam and rhoPimpleDyMFoam. recently, i have trired to use these two solver to run a rotating model. But I don't know why I can not get pressure change. I sure my model is no problem. because I have used other solvers to run this model and successfully get the result of pressure. Is there anyone know why? Thanks!
