Rooster New Member Ruaraidh Join Date: Jan 2021 Posts: 1 Rep Power: 0	Hi everyone, I'm currently working on a mold filling analysis where I need to implement a dynamically switching boundary condition based on the filling status of the adjacent cell (traction free to allow air to pass through and no slip for the filling phase) and I have tried to do so by implementing a udf for the shear condition at the wall. Is this the most efficient way to approach this problem? Thank you Last edited by Rooster; February 2, 2021 at 05:10.
