Detailed Description

Construct volumetric and surface integration rules for a given element using the Algoim library. The volume is define as the positive part of a level-set function(LSF) (lsfun argument in the constructor). The surface is defined as the zero level-set of the LSF.

Constructor & Destructor Documentation

◆ AlgoimIntegrationRule()

mfem::AlgoimIntegrationRule::AlgoimIntegrationRule ( int  o,
const FiniteElement el,
ElementTransformation trans,
const Vector lsfun 
)

Construct Algoim object using a finite element, its transformation and level-set function defined over the element using Lagrangian bases. The argument o provides the order of the of the 1D Gaussian integration rule used for deriving the vol/surface integration rules.

Definition at line 10 of file integ_algoim.cpp.

◆ ~AlgoimIntegrationRule()

mfem::AlgoimIntegrationRule::~AlgoimIntegrationRule ( )
inline

Destructor of the Algoim object.

Definition at line 121 of file integ_algoim.hpp.
