Moving mesh, change the B.C
 

Hi, everyone I am trying to simulate the valve using Moving Deforming Mesh(MDM). Fluent supports MDM, In-Cylinder model. It is possible to chage or delete the Boundary Condition(B.C) using In-Cylinder Model at arbitrary time. But I am not use In-Cylinder model. How can I change or delete the B.C at arbitary time? If I change the B.C using UDF, How can I specify the UDF? Regards.
