Detailed Description

Imports a 2D quadrilateral mesh from mesh generator gmsh.

This version reads the MSH ASCII file format (.msh). Parser reads only elements of type

1. 1-node point (elm-type 15),
2. 2-node line (elm-type 1),
3. 4-node quadrangle (elm-type 3),
4. 3-node second order line (elm-type 8),
5. 8-node second order quadrangle (elm-type 16),
6. 9-node second order quadrangle (elm-type 10).

Elements with other flags will be ignored. Curved edges are only supported up to order 2 and will be interpreted as circular edges.

Member Function Documentation

info()

virtual std::ostream& concepts::Import2DMeshGmsh::info ( std::ostream &  os ) const

virtual

Returns information in an output stream.

Reimplemented from concepts::Mesh.

scan()

concepts::Scan2* concepts::Import2DMeshGmsh::scan ( )

inlinevirtual

Returns a scanner over the cells of the mesh.

Postcondition

The scanner must be deleted after usage. This has to be done by the user.
