oomph::TimeHarmonicLinElastLoadedByHelmholtzPressureBCElement< ELASTICITY_BULK_ELEMENT, HELMHOLTZ_BULK_ELEMENT > Class Template Reference

A class for elements that allow the imposition of an applied traction in the equations of time-harmonic linear elasticity from a Helmholtz potential (interpreted as a displacement potential for the fluid in a quasi-steady, linearised FSI problem.) The geometrical information can be read from the FaceGeometry<ELEMENT> class and and thus, we can be generic enough without the need to have a separate equations class. More...

class oomph::TimeHarmonicLinElastLoadedByHelmholtzPressureBCElement< ELASTICITY_BULK_ELEMENT, HELMHOLTZ_BULK_ELEMENT >

The geometrical information can be read from the FaceGeometry<ELEMENT> class and and thus, we can be generic enough without the need to have a separate equations class.
