[Libmesh-users] time varying Dirichlet Conditions

[Manav B. <bha...@gm...>]

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
