Hi,
I am trying to identify the best approach to handle time-varying Dirichlet
conditions with libMesh. It appears that DirichletConstraints is used to create
a set of DofConstraintRow that is used after the nonlinear solves through
DofMap::enforce_constraints_exactly().
So, if time-varying DirichletConstraints are required, then the dof
constraints will have to be reinitialized at each time-step with the
DirichletCondition object returning the function values for that time?
Is there another way to do this without have to reinit the constraints?
Presently I am not using AMR. Would reinit of constraints at each time-step be
the best approach if AMR is used?
Thanks,
Manav
