This question already has an answer here:

I would like to mesh the region below in order to use it for a calculation by means of NDSolve. Could anyone help me to discretize this region for NDSolve using. Thank you very much.

Needs["NDSolveFEM"];

Rwg=7.0; RLiner=8.0; RRib=8.5; RExt=9.0; Theta1=0.0227; Theta2=0.00916;

Ω=ImplicitRegion[ !(x^2 + y^2>RLiner^2 && x^2 + y^2< RRib^2 && 0=0 && x^2 + y^2>=Rwg^2 && x^2 + y^2<=RExt^2 && y<=x Tan[Theta1]),{x, y}];

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • $\begingroup$ Aside from the fact that you have now included 0=0 in your list of conditions, how is this different from your last post? $\endgroup$ – Jason B. Mar 16 '16 at 8:47
  • $\begingroup$ No difference. I just was trying to give more visibility to my question. $\endgroup$ – Antony Mar 16 '16 at 10:30
