Does anyone know in what order the nodes are numbered in a mapped mesh in COMSOL, or where in the documentation node numbering conventions are explained?

I would like to do some post processing using the stiffness matrix, but can't figure which entry corresponds to which degree of freedom.

Thanks for the help!

Hi

I have never found that in the doc, but you can learn by starting with simple examples.

I mostly define groups in the GUI and then resolve the group indexes to identify the nodes, it was somewhat heavy but possible in 3.5 (there are several discussions and some code here try a search on the forum) . Still have to redo all this in V4 ;)

Good luck
