i have an almost square region.(adsbygoogle = window.adsbygoogle || []).push({});

By 'almost' i mean the edges are curvy, not completely straight.

i now need to solve the Helmholtz equation with Dirichlet boundary condition

what is the best numerical method?

how is Finite element, though i do not know what Finite element is
