[Libmesh-users] Don't prolong/restrict some system vectors

[Alexander L. <ale...@gm...>]

Is there a way to prevent prolongation/restriction of some System vectors
during mesh adaptation?  I see the *preserve* APIs but that doesn't look
like it does what I would want.... Basically I am performing grid
sequencing, obtaining initial guesses for fine grids based on solutions of
coarse grids. In a transient problem I have an old solution vector for
calculating time derivatives. Restricting this vector for the initial
coarse grid solution and then prolonging it for the fine grid solution
loses the fine detail from the previous time step.
