IRResultType oofem::TrabBoneNL::initializeFrom ( InputRecord ir)
virtual

Initializes receiver according to object description stored in input record.

This function is called immediately after creating object using constructor. Input record can be imagined as data record in component database belonging to receiver. Receiver may use value-name extracting functions to extract particular field from record.

void oofem::TrabBoneNL::updateBeforeNonlocAverage ( const FloatArray strainVector,
GaussPoint gp,
TimeStep tStep 
)
virtual

Declares the service updating local variables in given integration points, which take part in nonlocal average process.

Because value of single integration point influences nonlocal variables in several near integration points, it is suitable to compute these variables only once. These should be stored in integration point associated statuses. The implementation is left on derived classes. Provide material local strain increment - as is provided to computeRealStresVector. This allows to update internal vars to be averaged to new state

Parameters
strainVectorTotal strain vector in given integration point.
gpIntegration point to update.
tStepSolution step indicating time of update.

Implements oofem::StructuralNonlocalMaterialExtensionInterface.
