Meshing a Triangle with Tri elements
Meshing a Triangle with Tri elements
(OP)
Hello,
I am trying to mesh a triangular shell (100x100x100) with tri elements. (see the images in the Zip file)
1. When I specify a size of 3.125 per edge (Free mesh control), the resulting mesh is uniform and structured. See image free-size3125.jpg
2. When I specify a size of 2.0 per edge (Free mesh control), the resulting mesh is not uniform anymore. See image free-size2000.jpg
3. When I specify a size of 3.125 per edge with a structured mesh, the resulting mesh is "strange" . See image structured-size3125.jpg
Questions:
Can I control this problem (the non uniform mesh) without having to partition my structure?
What are the limits of CAE according to meshing techniques?
Thanks for your reply

I have just tried it.
It gives the same (bad) results.

According to the mechanical response, it is not a "bad" (consider the "") mesh. It even minimise the number of elements.
However, if i need to control that integration points should be on a line parralel to the triangle edge, it would be easier to get a structured (or mapped) mesh.
The only way I found to have a structured mesh was to partition the triangle in smaller triangles.
