void GRINS::SolidMechanicsAbstract::set_time_evolving_vars ( libMesh::FEMSystem * system )

virtual

Set which variables are time evolving.

Set those variables which evolve in time (as opposed to variables that behave like constraints). This is done separately from init_variables() because the MultiphysicsSystem must initialize its base class before time_evolving variables can be set. Default implementation is no time evolving variables.

Reimplemented from GRINS::Physics.
