Hello, I was able to sort the data but the PCGAMG does not seem to be working. I reconfigured everything from scratch as suggested and updated to the latest PETSc version, same results, I get the following error: [0]PETSC ERROR: Caught signal number 11 SEGV: Segmentation Violation, probably memory access out of range [...] [0]PETSC ERROR: --------------------- Stack Frames ------------------------------------ [0]PETSC ERROR: Note: The EXACT line numbers in the stack are not available, [0]PETSC ERROR: INSTEAD the line number of the start of the function [0]PETSC ERROR: is given.
