Hi Ramoni,
All EM induction methods solved numerically like finite differences are
difficult already because of the null-space of the curl-curl equations and then
adding air layers on top of your model also introduce another singularity.
These have been dealt with in the past by adding in some
We are solving the Direct Problem of Controlled Source Electromagnetics
(CSEM) using finite difference discretization.

Barry,
I configured PETSC with --with-debugging=yes. I think this is enough to block
any optimizations, right?
I tried both Intel and GNU compilers. The error persists.
I tried to change the preconditioner and use PILUT instead of BoomerAMG from
Hypre. Still, the error appears.
I noticed that I

If you can set an X Windows DISPLAY variable that works you can run with
-on_error_attach_debugger and gdb should pop up in an Xterm on MPI rank 16
showing the code where it is crashing (based on Valgrind Address 0x0 is not
stack'd, malloc'd or (recently) free'd there will be poin
Good Morning,
Thank you Matt, Jed, and Barry. I will looking into each of these suggestions a
report back.

Hello everyone,
I am trying to use Petsc coupled with Hypre BoomerAMG as preconditioner in our
in-house code to simulate the transient motion of complex fluid with finite
elements. The problem is that after a random number of iterations, an error
arises when the Hypre is called.
The error that
Hello,
Thank you for the response. I shall try it out.
