Hi,
I am a new user who has been using Libmesh for about 6 months on biomechanical
problems.
Does anyone know how to set the initial guess for a nonlinear equation by
designating a
known vector to be the initial guess? I am using the NonlinearImplicitSystem
Class in the
following manner:
NonlinearImplicitSystem system.
Vector soln;
loop
Step 1: // use soln as the initial guess for the system
Step 2: system.solve();
Step 3: soln = system.solution();
Step 4: //update system
end
My goal is to repeatedly solve the nonlinear system, with each iteration using
the
solution of its previous iteration as the initial guess. I am wondering which
particular
member functions or member variables I should use.
Any comments or suggestions would be greatly appreciated. Thank you very much
for your help.
Best,
Dafang
