This question might be silly. Is laplcae operator a positive definite system and easy to solve? Does it become ill-conditioned when mesh size and mesh quality reduce? "ill-conditioned" and "difficult to solve" are two different things. The condition number of the discretized Laplace operator

[deal.II] Fully distributed triangulation with GMSH

2023-03-14 Thread Kumar Saurabh
Hi, I am trying to perform the mesh partition using the mesh generated from GMSH. The generated mesh is quite big with around 500K elements. I am new to deal.ii. But I get the impression that the parallel::distributed::Triangulation works only from the quadrilateral/hexahedral meshes and use
