QUAD_MESH is a data directory which contains examples of files that define a quad mesh.
A quad mesh is a mesh of a 2D region based on quadrilaterals. A quad mesh can be defined by using two files:
The computer code and data files described and made available on this web page are distributed under the GNU LGPL license.
FEM_IO, a FORTRAN90 library which reads or writes node, element and data files defining a finite element model.
FEM2D_PACK, a FORTRAN90 library which handles various tasks associated with 2D finite element meshes.
MESH_BANDWIDTH, a FORTRAN90 program which returns the geometric bandwidth associated with a mesh of elements of any order and in a space of arbitrary dimension.
MESH_DISPLAY_OPENGL, a C++ program which reads files defining a polygonal mesh and displays an image using OpenGL.
QUAD_MESH, a FORTRAN90 library which handles meshes of quadrilaterals over a 2D region;
QUAD_MESH_ORDER1, a data directory of examples of QUAD_MESH files, a quadrilateral mesh in 2D, with an associated data value that is constant over each element of the mesh;
RECTANGLE is a simple rectilinear mesh using 30 points that form 20 quadrilateral elements in a 4x5 mesh of squares.
HOLE is a simple rectilinear mesh using 28 points that form 17 quadrilateral elements. The mesh includes a small interior hole.
SEMICIRCLE is a mesh in which the elements are not rectilinear. And because the mesh is in a semicircle, there is one row of "degenerate" quadrilaterals which are actually triangles.. It uses 37 points that form 32 quadrilateral elements.
WEB is a mesh in which the elements are not rectilinear. It looks a bit like a creepy spider web. It uses 100 points that form 81 quadrilateral elements.
