Member Function Documentation

LS_PCS_computedN()

virtual void oofem::LevelSetPCSElementInterface::LS_PCS_computedN ( FloatMatrix & answer )

pure virtual

Returns gradient of shape functions.

Implemented in oofem::Quad10_2D_SUPG, oofem::Tet1_3D_SUPG, oofem::TR1_2D_SUPG, and oofem::TR21_2D_SUPG.

Referenced by oofem::LevelSetPCS::pcs_stage1(), and oofem::LevelSetPCS::updatePosition().

LS_PCS_computeF()

virtual double oofem::LevelSetPCSElementInterface::LS_PCS_computeF ( LevelSetPCS * ls, TimeStep * tStep )

pure virtual

Evaluates F in level set equation of the form

\[ \phi_t + F(\nabla\phi, x) |\nabla\phi| = 0 \]

where for interface position driven by flow with speed u:

\[ F = u\cdot \frac{\nabla\phi}{|\nabla\phi|} \]

Implemented in oofem::Quad10_2D_SUPG, oofem::Tet1_3D_SUPG, oofem::TR1_2D_SUPG, and oofem::TR21_2D_SUPG.

LS_PCS_computeS()

virtual double oofem::LevelSetPCSElementInterface::LS_PCS_computeS ( LevelSetPCS * ls, TimeStep * tStep )

pure virtual

Evaluates S in level set equation of the form

\[ \phi_t = S(\phi) (1-|\nabla\phi|) = 0 \]

where

\[ S=\frac{\phi}{\sqrt{\phi^2+\epsilon^2}} \]

Implemented in oofem::Quad10_2D_SUPG, oofem::Tet1_3D_SUPG, oofem::TR1_2D_SUPG, and oofem::TR21_2D_SUPG.

LS_PCS_computeVOFFractions()

virtual void oofem::LevelSetPCSElementInterface::LS_PCS_computeVOFFractions ( FloatArray & answer, FloatArray & fi )

pure virtual
