In Finite Element Method (FEM) of Computational Electromagnetics, a complex domain is divided into many small elements, and the governing equations are approximated and solved across those pieces. Here, we demonstrate the method by using a triangular mesh to simulate an electromagnetic wave travelling through a lens.

For infinite boundary conditions use BEM (Boundary Element method) instead of FEM

Yeah, it's like zooming in on a puzzle, every tiny piece helps see the big picture better!

Première fois qu'avec mon bagage je comprends bien ce que vous exprimez. J'ai fait des modèles d'éléments finis sur FORTRAN pour la transmission de chaleur ainsi que des modèles plus lourds pour des structures 3D. Je peux donc mieux apprécier votre post ici. Merci !

Triangular mesh through a lens, clean work. How much does the solve time jump when you push the frequency up? That is where I always end up reworking my setup.
