Dynamic mesh: no slip condition

#1 · September 9, 2026, 12:52 am

Hello,

I have noticed that the non-slip condition for walls is lost while running a dynamic mesh. This is particularly problematic for inviscid simulations where the non-slip condition is required.

Is this a bug? Is there a way to overcome this issue?

Thanks in advance

Miguel

Hello,

You can select No Slip or Slip in boundary condition setup window.

If the boundary is moving you should select [Moving Wall] - [Mesh Motion], then movingWallVelocity condition is use instead of noSlip condition.

Thanks for the answer, that's super clear.
