protectedvirtual

Returns transformation matrix from local surface c.s to element local coordinate system of load vector components.

Necessary, because integration must be done in local coordinate system of entity (edge or surface). If no transformation is necessary, answer is empty matrix (default);

Parameters

IRResultType oofem::QSpace::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.
