Netgen 6.1 Experimental

[Deleted User]

Attached are some screenshots of some nice features of Netgen 6.1 Experimental. It has automatic quad dominate meshing. As always you can also do auto tet meshing and generate quality plots. You can generate quality plots for the new quad dominate meshes too.

You have to have Python 3.5 and MS C++ 2015 Redistributable installed for Netgen to work. If you use the very fine mesh setting and change the min mesh size from 0 to 1 you get very nice meshes. I also have to run Netgen as administrator to avoid issues of things not working in Netgen. The snapshot feature doesn't seem to work.

Attached are pictures of the mesh settings I used. I am not sure what the automatic z refinement option does. I tried meshing with and without that checked and didn't notice a difference. Also I check the second order element box but the element order is set to one. This generates elements with mid-side nodes. But I'm not sure what would happen if you left the second order element box unchecked and changed the element order to 2. I can't find any help for Netgen. If you don't want mid-side nodes on the elements then you can leave the element order at one and leave the second order element option unchecked.

The stl import isn't working for me either but the step import works fine.

Oh it looks like I was mistaken, the quad mesh is still only a surface mesh. I thought it was a solid. Bringing the mesh into Mecway, I see it is still only a surface mesh. Bummer

As far as I remember old Netgens has hexa dominant meshes capacity, but was not easy to achieve with complex shapes.
