Dear Sir,<br>Thanks to make a such efficient library to handle the complex mathematics.<br>I am Rahul and working on unstructured finite volume solver. The solver is able to solve both single zone and multi zone unstructured mesh using CSR Gauss Seidel.<br>
I successfully implement PETSc to solve on a single zone unstructured mesh i.e. serial implementation has done and tested.<br>Now I want to implement a PETSc on a multi-zone mesh.The mesh partitioning in multi-zone is done using a separate tool, Metis. The multi-zone mesh is read in solver.I don't understand how to do the global indexing for multi-zone mesh to form a global matrix required for PETSc.<br>
Your valuable suggestion and guidance is cordially appreciated. <br clear="all"><br><br>
