Hey,


I want to implement a time-varying pressure field on a piston-like cylindrical domain. I want to match a simple pressure curve I obtained from a similar geometry with specified piston velocity profile wrt time. Specifying the wall movement velocity profile, I am able to move one of the cylinder walls using mesh motion and increase/decrease the pressure based on it. Is it possible to obtain the same pressure curve by explicity changing the value of pressure in each cell during run-time? Will that create a problem (e.g. decoupling of velocity and pressure) during simulation?


I looked at different boundary conditions and one looked like what I need is timeVaryingMappedFixedValue. If I specify all the points in my domain and set them to a fixed pressure value as a function of time would that solve the problem, or am I thinking too straightforward?


Best,
