I wonder if it is possible to pass solution vector to refined-meshed....
I am solving non-linear problem with iterative method.
I'd like to use coarse mesh solution as a initial solution to find accurate
solution fast.
However, my present code sets up system again on every refinement cycle.
So, I lose all solution that I had in coarse mesh.
I think it is really helpful for me if I knew a way to pass the previous
solution to as a initial solution for next iterative method.
I think it might be complicated... first vector size of solution might
different when mesh is refined....
is there anyone who has idea on this ?
Take a look at step-15 -- it does exactly this, using the SolutionTransfer
class.
