Geometry and Meshing#
Author: Jonathan Hargreaves
This part of the site is currently under development. Its content is incomplete.
This page will discuss the differences between geometry and a mesh It will also signpost the sub-pages.
Exact definition of geometry (correct curvature etc.)
Surface sections can be large w.r.t. wavelength
Approximate version of geometry
nodes ‘sampled’ from geometry then curvature of elements is interpolated
Elements should be small w.r.t. wavelength
I have some cateye geometries & meshes created in Gmsh if we prefer to avoid COMSOL ones?
