virtual void oofem::HeavisideFunction::giveJump ( std::vector< double > &  oJumps) const

Returns the discontinuous jump in the enrichment function when the lvel set function changes sign, e.g.

1.0 for Heaviside, 2.0 for Sign and 0.0 for abs enrichment. Used for combination of cohesive zones and XFEM.

Implements oofem::EnrichmentFunction.
