Hi,
I'm investigating skin effect in a nonlinear material.
Skin effect means high concentration of current in a very thin layer.
So I need to represent this very thin layer with a high number of elements.
I discovered the "boundary layer mesh" option.
Now I have a few questions on meshing with this possibility:
1. The mesh-quality I obtain is really bad, especially in the important (thin) regions. This seems evident to me because the mesher produces many elements that differ from the ideal square-shape of rectangle-elements.
How do I handle this effect? Is there a possibility to significantly improve mesh-qualtity?
2. How can I change the length of rectangle-elements in tangential direction? The "boundary layer properties" node only enables control in normal direction...
Thx beforehand,
Daniel
