Re: [deal.II] Wave front not propagating through mesh modification on step 23, is Affine constraints wiping out my solution?

Just to close this out in case others run into the same problem. The culprit was me declaring a local vector variable system_rhs in WaveEquation::run (). A c

Re: [deal.II] mesh_generator

Dear Simon and prof. Bangerth Thanks for your kind replies. The issue finally turned out to be that I set a 'smoothness' when I defined the triangulation ( my supervisor found it, he is a deal ii deep lover XD). I have a further question though. The background is that, I am doing some electrom
