QMG

Description:

QMG is free software available on the Web for fully automatic unstructured finite element mesh generation in two and three dimensions. It can generate meshes for complex domains with curved boundaries and nonmanifold features. QMG 2.0 can be run either from the shell, under Tcl/Tk (a freeware scripting language) or MATLAB. The MATLAB version includes a simple finite element solver. QMG is written in primarily in C++.

Platforms:

Needs a C++ compiler (and the scripting language TCL). QMG has been installed on various Unix platforms including Sun Sparc and HP9000, and Windows NT.

Notes:

QMG also includes geometric modelling routines and an FE solver. The package uses MATLAB (qv) as a front end, however the mesh generation routines can be run independently of MATLAB. The FE solver is written entirely in MATLAB. Output is in VRML, and requires a VRML 1.0 viewer.

The main new feature of QMG2.0 (compared to QMG1.1) is its ability to handle true curved geometry. QMG2.0 permits boundaries defined by Bezier curves, triangular Bezier patches and quadrilateral tensor-product Bezier patches. Representations of certain simple curved geometries (cylinders, spheres, tori) using Bezier patches are shipped with QMG.
