Hello
I have an optimization problem for which at a certain iteration, PETSc fails to
build the preconditioner. I would like to catch that error and print my
EquationSystem to disk so I can rerun the PETSc solve at that optimization
iteration from the start. I cannot just rerun my optimization and write to disk
at the iteration I know it is going to fail. The reason is that in parallel the
optimization slightly differs every time I run it so the iteration it is going
to fail at keeps changing. Maybe something along this lines:
try{
system.solve()
}
catch(...){
EquationSystem & es = system.get_equation_systems();
es.write("eq_output.xdr")
}
Thanks
Miguel
