HOUSTON, TX – March 6, 2007 – Visual Numerics, Inc., celebrating 36 years of producing advanced numerical analysis and visualization software, today announced the availability of PDE2D, a partial differential equation (PDE) solver authored by University of Texas-El Paso Mathematics Professor Dr. Granville Sewell, through Visual Numerics’ Affiliated Products and Services (VNIAPS), a brand new channel program for downloadable high-quality software. Through the Visual Numerics Storefront, users purchase and download electronic copies of PDE2D, receive technical support from Dr. Sewell through Visual Numerics Forums, and engage in topical discussions about PDEs and PDE2D.

“Using VNIAPS to distribute PDE2D will open up many more global sales opportunities for me than I could have garnered otherwise,” said Dr. Sewell. “VNIAPS is a reliable, easy-to-use channel program and will allow me to focus on my PDE2D software and supporting PDE2D users.”

Partial differential equations are used to formulate problems that occur in diverse areas, such as heat conduction, stress analysis, electronics, fluid flow, weather prediction, and financial engineering. Dr. Sewell’s software package PDE2D solves general nonlinear, time-dependent, steady-state and eigenvalue systems of partial differential equations in 1D intervals, general 2D regions and a wide range of simple 3D regions. The software features an interactive user interface, which makes it very easy-to-use, yet PDE2D users have all the flexibility of Fortran at their disposal. Collocation and Galerkin finite element methods are used, on automatically generated meshes of higher order elements, so that at least fourth order accuracy is available for all problems. PDE2D has extensive built-in graphics, and also provides an interface to MATLAB®'s graphical and post-processing abilities.

“By offering high quality downloadable software like PDE2D and a discussion forum with the author and other users, we’re providing a valuable channel for sharing mathematical software knowledge and connecting users with solutions for solving complex problems,” said Phil Fraher, president and CEO of Visual Numerics. “In turn, our VNIAPS program provides a powerful channel for software authors to sell and support their products to a wider audience – a win-win proposition for everyone.”

Pricing, Availability & Support
PDE2D can be purchased and downloaded worldwide from the Visual Numerics storefront at http://buy.vni.com. Single-user licenses are US $1,500 with academic and multi-license discounts available. Additional product information about PDE2D and a trial version are located at http://www.vni.com/products/affiliated/index.html. Dr. Sewell will provide user support for PDE2D through the PDE2D Forum within the VNI Forum at http://forums.vni.com.
