# Mesh refinement in Comsol

When I use the refine or extremely refine mesh options in Comsol multiphysics software for 3D simulation it uses an overwhelmingly large number of degrees of freedom, for example, 17 million degree of freedoms, that for a solution of the problem for each of freedom degree the Comsol evaluate (for example, in RF model) all of the electric and magnetic-field components, and another parameter that I don't need. How can I control refinement in Comsol for the components that I need?

 This is another question where you might get a better response on the COMSOL forums, though I hope someone here might be able to answer it. – Geoff Oxberry♦ Jun 17 '12 at 14:30
