Mesh of very thin geometries

Hi, I would like to study in a very thin geometry. It is basically a disk (diameter 5mm, thickness 1um) with 4 rectangular channels (width 1mm, thickness 1um). I understand that cannot use the...

Re: Mesh of very thin geometries

Hi How about this? I made a work plane where I drew the shape, made a union, keeping interior boundaries, and extruded it 1 µm. Now swept mesh is no problem. Attached a screen shot and the model file....

Re: Mesh of very thin geometries

Hi, Thank Lasse for your help. I don't have 4.4 yet but I will get it soon. I can see that it works well from your screenshot. However, I should have been more precise in the description because it...

Re: Mesh of very thin geometries

Can you elaborate on how you did this, Jeff? This is exactly what I am trying to do. Modeling a membrane 2µm thick over a suspended structure 20µm thick with different geometry for a MEMS application....
