[petsc-users] Question about PETSC with finite volume approach

Dear Petsc-User, Hi, I am Seungjin Seo, and I am trying to use PETSC to solve my problem. I want to solve a heat conduction equation using finite volume methods in 2D and 3D. I am going to import Gmsh files. Can you recommend me an example case for this purpose? Also, can I set different

Re: [petsc-users] Question on DMPlexCreateSection for Fortran

Hi Matt, To test the Segmentation Violation problem in my code, I modified the example ex1f90.F to reproduce the problem I have in my own code. If use DMPlexCreateBoxMesh to generate the mesh, the code works fine. However, if I use DMPlexCreateGmshFromFile, using the same mesh exported from
