[petsc-users] [SLEPc] Performance of Krylov-Schur with MUMPS-based shift-and-invert

2018-02-19 Thread Thibaut Appel
Good afternoon, I am solving generalized eigenvalue problems {Ax = omegaBx} in complex arithmetic, where A is non-hermitian and B is singular. I think the only way to get round the singularity is to employ a shift-and-invert method, where I am using MUMPS to invert the shifted matrix. I am u

[petsc-users] how to check if cell is local owned in DMPlex

2018-02-19 Thread Danyang Su
Hi Matt, Would you please let me know how to check if a cell is local owned? When overlap is 0 in DMPlexDistribute, all the cells are local owned. How about overlap > 0? It sounds like impossible to check by node because a cell can be local owned even if none of the nodes in this cell is local

[petsc-users] Compiling problem after upgrading to PETSc 3.8.3
