tk::MeshReader class

Contents

Polymorphic mesh reader class for connecting to various mesh readers

This class uses runtime polymorphism without client-side inheritance: inheritance is confined to the internals of the this class, invisible to client-code. The class exclusively deals with ownership enabling client-side value semantics. Credit goes to Sean Parent at Adobe.

Function documentation

tk::MeshReader::MeshReader(const std::string& filename) explicit

Parameters
filename in Input mesh filename

Constructor Dispatch constructor call to various low level mesh readers by creating child class and assigning to base to be used in polymorphic fashion.

void tk::MeshReader::readMeshPart(std::vector<std::size_t>& ginpoel, std::vector<std::size_t>& inpoel, std::vector<std::size_t>& triinp, std::unordered_map<std::size_t, std::size_t>& lid, tk::UnsMesh::Coords& coord, int numpes = 1, int mype = 0)

Public interface to read part of the mesh (graph and coords) from file

Total number of PEs defaults to 1 for a single-CPU read, this PE defaults to 0 for a single-CPU read.
