Dear USERS,
When I am trying a parametric solver in perpendicular wave with paramaetric name lamda0; it gives the singular matrix error. But when Im doing the same thing in in in-plane waves then it does not give any error? What could be the reason? I am struggling with comsol...........can anyone suggest any book or document or just describe the solution here!

Thanks

I get this error message often if my mesh is to croase (using perpend. wave < eigenfreuency analysis).
It is helpful to read RFmodule_ReferenceGuide.pdf, RF-Module-ModelLibary.pdf. Another option is searching in the RF forum, because this is a known problem...

hfc!
