How can i to do a mesh with element quadrilateral quadratic 8 nodes? What the better V4.2a or 4.3 , or other to do the mesh. is it possible export matrix coordinate and topological? . In V.3.5a it is possible.
Thanks for you help

Hi Vera,

2D quadratic Lagrange interpolation in COMSOL results in 9-node quadrilateral elements. That is very close to the 8-node quadrilateral and in many cases performs better.

Hi, Thanks for your help!

But, i still need to know: How to export the topological matrix and coordinates?

regards
