Mesh Update - Higly deformed mesh; maybe an adaptive mesh?
Posted: 14 Mar 2014, 17:13
Hej,
I am interested on the gas motion due to a cyclic movement of a wall.
In order to keep things simple I run a simple case in 2D.
So it is defined:
- Navier-Stokes
- Heat Tranfer
- Mesh Update
With small wall movements it smoothly runs; however when the mesh is deformed beyond a certain point it crashes. In other software it is possible to input different meshes in order to jump form one to the other to avoid over-deforming it. May be How generate a new mesh when it becomes too contrained?
I have been reading everything about "adaptive mesh" in Elmer however I do not succeed.
How can I define a mesh (or a joint of meshes) which can handle such a deformation?
I attach my working files.
Thanks in advance,
