Hi Paul,
Thanks for your tips. I extracted the current_solution in the follow
way, but I got an all-zero result when running with multiple processors.
Only the single processor yielded the right result. Do I miss something?
NonlinearSystem system;
PetscVector v;
v.init( *(system.current_local_s
I've done something similar to this. You'll need to catch the error the
solver throws (ConvergenceFailure, I think, double check), then reset the
solution to your cached, good solution. This can be done by grabbing the
solution vector from the system. Don't forget to close() the solution
vector onc
Hi folks,
Does anyone know how to set the initial guess solution of a nonlinear system
from a known vector? My code is in the following manner:
NonlinearImplicitSystem system.
Vector v1 = system.current_solution(); //Step1
system.solve();
if the nonlinear solve diverges
Reset system.current_
