Meshing problems

Magneto

Hello all,

 

I'm have build up a 3D model which 4 parts in it. This model I can mesh and solve without any problems. Now I had split 1 part into 3 party, because of different material behavoiurs. These three parts contact at the splitting surfaces. Because I was not able to mesh this geometry, I have insert a 0,5mm air gab between the parts. Now I can mesh the geometry, but without the infinitiy box. If i complete the infinity box first, it comes to a problem at meshing the volumes: 'Meshing by inserting nodes has aborted. Please check mesh on lines: 331 43 44'

 

My question is now: What can I do to avoid the meshing problems? Do I need the 0,5mm air gab between the parts?

 

Thanks for your support.

Hello,

In your case you need to refine the mesh between the device and infinite box. For example create a line discretization and affect it to the line between the infinite box and your device.

Also you can change the mesh generator. To do it:

Tools >> mesh and geometry options >> edit: mesh: you can select a method for automatic  mesh  generator

Hope this will help you.

Best regards.

Hello,

 

thank you for your fast answer. Your advise helps me a lot.

 

But do I have to model the airgab between two parts always, although the parts are in contact in reality?

Hello,

 

I guess you do not.

When you cut the solid into 3, next in my opinion you are supposed to assembly them. They remain different solids so you can assign different volume regions. Then Flux should mesh domain with no error.

If you need an air gap, you can assign the Air gap region face region for surfaces in between volumes in splitted solid.
