2D remeshing workflow

Hey everyone,

 

I was wondering, what is a common workflow for remeshing 2D shell meshes.

For example, when you work with shell meshes of sheet metals, but you do not have CAD data. You maybe have *.key or *.k files with FE model data and you want to work with this.

Sometimes you have to change the mesh (add/delete openings or change the mesh size)

 

What is a good workflow for this task? Do you see different workflows in terms of a) time needed to complete the task and b) quality of resulting mesh ?

 

Right now, this is how I did it:

1) Import FE data to HM

2) Tools > Features:

  • Using 'connected' gave good results
  • Create plot elements and edit them, if necessary

3) Geometry > Surfaces > From FE:

  • Using the feature-plot-elements

4) Delete old mesh

5) Modify surface, if necessary

6) Automesh on surface

 

This takes quite some work.

 

When I tried to remesh the existing elements, I had a lot of failed areas and I cannot modify the geometry that easily.

 

The problem is, the surfaces based on a rough mesh is realy rough and not a good base for a fine mesh.

 

 

I think this is a common task. Is there a better workflow?
