MeshUpdate

Post by kimsongoik »

Dear Elmer group
Hello
I’m using MeshUpdate solver and want to know how is it possible to force the nodes on target boundary 1 to follow x-motion of nodes on target boundary 2 (the mentioned boundaries are opposite to each other and have the same number of nodes)?

Boundary Condition 1
Target Boundary = 1
.
.
End
Boundary Condition 2
Target Boundary = 2
.
.
End

Best wishes,
KimSongOik

Hi Kim

Do you mean that you would like to have periodic BCs for the mesh deformation in x-direction? This may be obtained by

Code: Select all

Boundary Condition 1
  Target Boundary = 1
End

Boundary Condition 2
  Target Boundary = 2
  Periodic BC = 1
  Periodic BC Mesh Update 1 = Logical True
End
The periodicity should work even if you would have nonconforming meshes.
