virtual

Computes the contribution of the given load at the given boundary surface in global coordinate system.

In general, the answer should include only relevant DOFs at the edge. The related is giveBoundaryLocationArray method, which should return corresponding code numbers.

Note: Elements which do not have an contribution should resize the vector to be empty.

Parameters

answer	Requested contribution of load.
load	Load to compute contribution from.
boundary	Boundary number.
type	Type of the contribution.
mode	Determines mode of answer.
tStep	Time step when answer is computed.
global	if true (default) then contribution is in global c.s., when false then contribution is in element local c.s.

virtual

Computes characteristic vector of receiver of requested type in given time step.

If element has no capability to compute requested type of characteristic vector error function is invoked.

Parameters

answer	Requested characteristic vector.
type	Id of characteristic component requested.
mode	Determines mode of answer.
tStep	Time step when answer is computed.

void oofem::Tr21Stokes::updateYourself ( TimeStep * tStep )

virtual

Updates element state after equilibrium in time step has been reached.

Default implementation updates all integration rules defined by integrationRulesArray member variable. Doing this, all integration points and their material statuses are updated also. All temporary history variables, which now describe equilibrium state are copied into equilibrium ones. The existing internal state is used for update.

Parameters

tStep Time step for newly reached state.
