Detailed Description

This class provides all data required for a physics package (e.g.

an FEMSystem subclass) to perform local element residual and jacobian integrations.

This class is part of the new DifferentiableSystem framework, which is still experimental. Users of this framework should beware of bugs and future API changes.

Member Function Documentation

◆ _do_elem_position_set()

void libMesh::FEMContext::_do_elem_position_set ( Real theta )

private

Uses the coordinate data specified by mesh_*_position configuration to set the geometry of elem to the value it would take after a fraction theta of a timestep.

This does the work of elem_position_set, but isn't safe to call without _mesh_sys/etc. defined first.

Referenced by elem_position_set().

◆ _update_time_from_system()

void libMesh::FEMContext::_update_time_from_system ( Real theta )

private

Update the time in the context object for the given value of theta, based on the values of "time" and "deltat" stored in the system which created this context.

◆ add_localized_vector()

void libMesh::DiffContext::add_localized_vector	(	NumericVector< Number > &	localized_vector,
		const System &	sys
	)

Quadrature rules for element sides The FEM context will try to find a quadrature rule that correctly integrates all variables.

We prepare quadrature rules for each element dimension in the mesh.

◆ system_time

const Real libMesh::DiffContext::system_time

inherited

This is the time stored in the System class at the time this context was created, i.e.

the time at the beginning of the current timestep. This value gets set in the constructor and unlike DiffContext::time, is not tweaked mid-timestep by transient solvers: it remains equal to the value it was assigned at construction.

◆ time

Real libMesh::DiffContext::time

inherited

For time-dependent problems, this is the time t for which the current nonlinear_solution is defined.

FIXME - this needs to be tweaked mid-timestep by all transient solvers!
