remeshing the results of a simulation in hypermesh or ls prepost.

[Behdad.S]

Hello everybody,

I have a mesh like a picture below. How can I change the element size or remesh the model in Hypermesh? I know that I can do it one by one. But is there any way to do it faster concerning the current mesh geometry?

So the mesh wasn’t created in Hypermesh ? I think that the easiest way would be to recreate this geometry (contour) and mesh it again.

 

[Behdad.S]

No, the mesh is not created in Hypermesh. It is the result of a simulation, which consists of the stress and strain state from the last simulation step.
I need also to have this information in the new mesh.

Remeshing is the straightforward part but what you are really after is "mapping" of the stress/strain fields from one mesh to another.

Yes, Exactly. that is the main problem. I used the Automesh of the Hypermesh. It works well. However, I can not map the stress and strain yet.

That is because you are using the wrong tool for the job.

Again, this is NOT much of a pre-processing matter. You need to look into the documentation of the solver you are using (Abaqus/ANSYS/DYNA/COMSOL/..) and find out how to map results from one mesh to another.

I'm not sure how useful the results from a mesh like that are going to be.
