IRResultType oofem::MixedGradientPressureBC::initializeFrom ( InputRecord * ir )

virtual

Initializes receiver according to object description stored in input record.

The input record contains two fields;

devGradient #columns { d_11 d_22 ... d_21 ... } (required)
pressure p (required) The gradient should be deviatoric and in Voigt notation. The prescribed tensor's columns must be equal to the size of the center coordinates. The size of the center coordinates must be equal to the size of the coordinates in the applied nodes.
