I am simulating an oscillating boundary problem in 2D. For that I have to use dynamic meshing option. My flow will start because of the disturbance of the boundary. I am trying to give motion to the wall boundary but there seems to be some problem with dynamic mesh zones. What boundary conditions should I give? And which UDF should I hook to just disturb the boundary and keep the body steady whilst the boundary is oscillating. Please help..... I need it very badly

Have you already written a UDF??

Yeah I already made a udf. But because of it now my boundaries are moving as a rigid body with simple harmonic motion. I want them to deform.(Expand and contract). I ran a simulation with rigid body. It was as per expectations but then I started having problems with ANSYS workbench. Whenever I open the designmodeler, it gives me some jscript error. What should I do?
