To clarify, I call PETSc initialize and PETSc finalize everytime I call
SLEPc:
PetscInitializeNoPointers(argc,args,nullptr,nullptr);
SlepcInitialize(,,static_cast(nullptr),help);
//calling slepc
SlepcFinalize();
PetscFinalize();

Dear PETSc team,
When I called SLEPc multiple time, I eventually got following error:

Dear PETSc users,
We use PETSc as part of a finite element method program and we are trying
to properly implement Dirichlet boundary conditions for non-linear,
transient problems. We find that when we use a line search method it also
changes the non-zero solution value of Dirichlet nodes as it

Hello,
Thank you both for your comprehensive replies.
Matt:
Thanks for the rundown, I will take a look at PyLith and its cohesive element
impls.
Blaise:
The project is still in very early stages as you can tell, so everything is up
in the air. Currently we are weighing using a cohesive
Looks like a completely different location now. Are you calling MatAXPY ? If
so perhaps the arguments are wrong. One is likely a parallel matrix and one
sequential.

This is more useful and you are getting a new error. Maybe the old error is
fixed.
It looks like you are trying to copy a matrix into another but they have
different communicators. For example, one is created with MPI_COMM_WOLD
and the other with PETSC_COMM_WORLD.

Do you have a small test example?

Dear Mark,
I updated Petsc and again, here's the error:
[0]PETSC ERROR: - Error Message

[0]PETSC ERROR: Arguments must have same communicators
[0]PETSC ERROR: [1]PETSC ERROR: - Error Message
I don't know what is going on here. There was an update to this function
about a year ago, so that might fix your problem.
We would need you to test with a current version.

Hi all,
I am trying to find off block diagonal entries of a matrix and I am
trying to use MatFindOffBlockDiagonalEntries. However, although my
matrix is not NULL, I am getting an error message as follows:
