Hi Everyone i am new to this forum..the reason why i am here is a problem, i really want to discuss here. I am working on a thesis on optimization of a circular fin. But i want to know how can i start to solve the heat equation. the preferred method to solve the problem is Numerical method(Finite difference Method). Now the main problem is the grid generation in the circular surface. Please someone tell me how do i generate the grid... hope i will get some quick response.
