void RichardsSeff2gasRSC::d2seff ( std::vector< const VariableValue * >  p, unsigned int  qp, std::vector< std::vector< Real >> &  result  ) const

virtual

second derivative of effective saturation as a function of porepressure

Parameters

p	porepressure in the element. Note that (*p[0])[qp] is the porepressure at quadpoint qp
qp	the quad point to evaluate effective saturation at
result	the derivtives will be placed in this array

Implements RichardsSeff.
