A question about dynamic mesh
 

I have a question about “rigid dynamic mesh”(sorry ,I don’t know the exactly name ,the meaning is that the grid moved without deformation but entirety)


The problem is :
1 I have a complex model, the flow is outflow.
2 I want to calculate the pitching movement
3 I don’t want to use the smoothing, layering, remeshing command in the Fluent.
4, I want the whole mesh move without deformation
What should I do ?
Does the Fluent with UDF can solve my problem?
Should I do some work on boundary condition?
Can someone give me an example about the 2D airfoil.


Need your help
Thank you

In fluent there is 'Cell Zone Condition' where you can select 'Mesh Motion' and input the speed or rotational speed etc.

however,if i choose the mesh motion method to move the whole mesh, how to set the boundary conditions ?
p.s.if i use the sliding mesh, then the problem can be solved by what you say before

Setting up boundary conditions like pressure and velocity have nothing to do with dynamic mesh. You can always setup boundary conditions as you would do in normal case and in addition to that assume that your domain is moving.
