I am thinking of doing something similar by first re-constructing solution vectors from the saved file and then using them along with dof locations (of the fine mesh) to set the initial condition for a fine mesh.

So is your fine mesh a refinement of the coarse one? If not, you may want to look at FEFieldFunction.


Is there any better way to accomplish what I desire? Also, will this approach work well for curved manifolds, or do I have to take additional steps to somehow reload the manifold data separately? Any help would be gladly appreciated.

You would have to attach manifolds to the triangulation object that is being reconstructed, before reconstruction.

Best
