Member Data Documentation

◆ c

Eigen::Vector3d Mesh::mesh::c

isobarycenter

◆ fac

std::vector<Facette::Fac> Mesh::mesh::fac

face container

◆ l

Eigen::Vector3d Mesh::mesh::l

lengths along x,y,z axis

◆ node

private

node container: not initialized by constructor, but later while reading the mesh by member function init_node

◆ node_index

std::vector<int> Mesh::mesh::node_index

private

Index of a node in the node vector. This vector is itself indexed by the node position in the *.msh and *.sol files. In other words, the node found at file_idx in a file is stored as node[node_index[file_idx]].

This is the inverse of the permutation we applied when sorting the nodes.

◆ tet

std::vector<Tetra::Tet> Mesh::mesh::tet

tetrahedron container

◆ vol

double Mesh::mesh::vol

total volume of the mesh
