Mesh displacement in ALE
Mesh displacement in ALE
(OP)
Hi,
There is something I don't understand with the 2D ALE adaptive meshing:
I have two different models using this method but two different results.
First model: a first step without ALE, a second with ALE: one inflow and one outflow eulerian boundary regions. The mesh moves with the material and the geometry is updated.
Second model: a single step with ALE, the same inflow and outflow eulerian boudary surfaces. This time the mesh doesn't move with the material !!! : The stresses change with the time but the geometry remains the same !!!
What can influence the displacement of the mesh in an ALE ????
Thx

RE: Mesh displacement in ALE
Could you tell me how to define inflow and outflow eulerian boundary in ALE?
Thank you so much!

RE: Mesh displacement in ALE
I MADE A MODEL IN ABAQUS CAE FOR FRICTION STIR WELDING PROCESSING BUT IN INFLOW AND OUTFLOW DEFINITION I HAVE PROBLEM AND MY ERROR IS "An Eulerian boundary region cannot overlap a sliding boundary region" . I ATTACH MY .inp FILE, PLEASE HELP ME!
Thank you so much.
