◆ build_bases() [1/2]

static int polyfem::basis::LagrangeBasis3d::build_bases ( const mesh::Mesh3D &  mesh,
const std::string &  assembler,
const int  quadrature_order,
const int  mass_quadrature_order,
const Eigen::VectorXi &  discr_order,
const bool  serendipity,
const bool  has_polys,
const bool  is_geom_bases,
const bool  use_corner_quadrature,
std::vector< ElementBases > &  bases,
std::vector< mesh::LocalBoundary > &  local_boundary,
std::map< int, InterfaceData > &  poly_face_to_data,
std::shared_ptr< mesh::MeshNodes > &  mesh_nodes 
)
static

Builds FE basis functions over the entire mesh (P1, P2 over tets, Q1, Q2 over hex).

Polygonal facets with > 4 vertices are dealt later on by the PolygonalBasis3d class.

Parameters
[in]meshThe input volumetric mesh
[in]assemblerThe pde to solve
[in]quadrature_orderThe quadrature order
[in]mass_quadrature_orderThe quadrature order for mass
[in]discr_orderThe order for each element
[in]serendipityUses serendipity bases or not (only for hex)
[in]has_polysDoes the mesh has polygons, if not the interface mapping is not necessary
[in]is_geom_basesFlag to decide if build geometric mapping or normal bases, used to decide if the nodes are important
[out]basesList of basis functions per element
[out]local_boundaryList of descriptor per element, indicating which edge of the canonical elements lie on the boundary of the mesh
[out]poly_edge_to_dataData for edges at the interface with a polygon (used to build the harmonics inside polygons)
Returns
The number of basis functions created.
