updateBeforeNonlocAverage()

void oofem::IDNLMaterial::updateBeforeNonlocAverage ( const FloatArray & strainVector, GaussPoint * gp, TimeStep * tStep ) const

overridevirtual

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

strainVector	Total strain vector in given integration point.
gp	Integration point to update.
tStep	Solution step indicating time of update.
