Member Function Documentation

MaterialStatus * oofem::IsotropicHeatTransferMaterial::CreateStatus ( GaussPoint gp) const
virtual

Creates new copy of associated status and inserts it into given integration point.

Parameters
gpIntegration point where newly created status will be stored.
Returns
Reference to new status.

Reimplemented from oofem::TransportMaterial.

Reimplemented in oofem::CemhydMat, oofem::HydratingConcreteMat, and oofem::HydratingIsoHeatMaterial.

void oofem::IsotropicHeatTransferMaterial::giveCharacteristicMatrix ( FloatMatrix answer,
MatResponseMode  mode,
GaussPoint gp,
TimeStep tStep 
)
virtual

Computes characteristic matrix of receiver in given integration point.

The algorithm should use temporary or equilibrium history variables stored in integration point status to compute and return required result.

Parameters
answerContains result.
modeMaterial response mode.
gpIntegration point.
tStepTime step (most models are able to respond only when tStep is current time step).

double oofem::IsotropicHeatTransferMaterial::giveCharacteristicValue ( MatResponseMode  mode,
GaussPoint gp,
TimeStep tStep 
)
virtual

Computes the characteristic value of receiver in given integration point, respecting its history.

The algorithm should use temporary or equilibrium history variables stored in integration point status to compute and return required result.

Parameters
modeMaterial response mode.
gpIntegration point.
tStepTime step (most models are able to respond only when tStep is current time step).

void oofem::IsotropicHeatTransferMaterial::giveFluxVector ( FloatArray answer,
GaussPoint gp,
const FloatArray grad,
const FloatArray field,
TimeStep tStep 
)
virtual

Returns the flux for the field and its gradient.

Todo:
{ Should the field variable just be a scalar? This might change when we rethink the coupled-fields approach. Now its either just [temperature], or [temperature, concentration] so to cover both cases there is a floatarray. }
Parameters
answerThe flux.
gpGauss point.
gradGradient of the primary field, usually the main input.
fieldThe value of the field itself.
tStepActive time step.
Todo:
Shouldn't the conductivity typically depend on the primary field and/or its gradient?
