QUAD - GEN

Automatic, general-purpose quadrilateral mesh generator.

Yes ! We will provide you with complete source codes !

What is QUAD-GEN ?

A great variety of finite element software is being developed throughout the world. While major efforts of development teams are usually concentrated on the mathematical cores of the codes, accurate and reliable mesh generation very often requires significant even more significant investment.

It is a recognized fact that quadrilateral elements have many advantages over triangles, especially in terms of their accuracy in evaluation of stress fields. Triangular mesh generators are plentiful, available at little or no cost from public domain. On the contrary, source codes of a commercial-quality quadrilateral generator is difficult to obtain. Being fully aware of this situation, we have developed a variety of such generators; each of them is flexible and easy to include into other software systems.

QUAD-GEN is fully automatic quadrilateral mesh generator, designed specifically with the purpose of inclusion into your finite element applications at the source code level. You can create your own point-and-click interface, allowing creating domain's boundary. After that, simple and straightforward data structures will have to be passed into QUAD-GEN, and the rest is done automatically. Two data structures: for nodes and elements, are returned and can be further used as necessary.

For generation of highly anisotropic, non-structured quadrilateral finite element meshes, we developed ANISO-QUAD mesh generation program. Our most recent, flexible and universal product QUAD-BUILD 5.0 can also be used for general-purpose problems, especially from the area of structural engineering.

What advantages does QUAD-GEN have ?

QUAD-GEN is an accurate and reliable program, capable of creating quality and often very large quadrilateral meshes. Its main features are:

- ability to handle regions divided to several subregions with different physical properties. This comes useful in several areas of science, for example, in geophysics, where cross-section of the Earth's crust may reveal several layers of different materials;

- the process is fully automatic, requiring no interference from the user as soon as the input data structures are prepared;

- the outer boundaries of subregions, as well as inter-layer division lines, can be segments of straight lines or arcs, and/or their arbitrary combinations. Boundaries of great complexity can be described that way.

All our codes are written in ANSI C and will compile and run on any UNIX and Windows platform.They are also fully commented, allowing easy modification at user's discretion. Below you will find several simple examples, and more examples can be found where descriptions of ANISO-QUAD, QUAD-BUILD 5.0 and QUAD-SURFACE (our 3D product) are provided.

Delivery, licensing and support.

QUAD-GEN is completely developed by our company and contains no third party code. We provide full, one-off commercial licence, and support for 12 months. If you purchase QUAD-GEN, you will be provided with:

- complete, fully commented source code in C;

- a User Manual, containing detailed description of input and output data structures and an example driver program;

- and a graphical visualisation program QUAD-PRO that will allow you displaying domains that are to be meshed, as well as generated quadrilateral meshes. 

Finally, our "try-before-you-buy" policy. If you send us several examples of your domains, we will run QUAD-GEN on them and send you the meshes created. If you are satisfied with results, you can then purchase QUAD-GEN.
