From: john%ghostwheel.unm.edu@ariel.unm.edu (John Prentice) Our group at Amparo Corporation develops computer codes to model the continuum physics of solids at extreme pressure and high strain rates. The traditional users of our codes have been researchers in the DoD and DoE working on the design of conventional weapons and armor. We would like to push out a bit as well into areas like the shock synthesis of materials and high pressure research. We currently have a new code under development which employs domain decomposition techniques for modeling large deformation solid dynamics and which has coupled into it a library of constitutive models for solids. It is also fairly easy to add constitutive models. We expect to be beta testing late this spring or early summer. The code is three dimensional, but can be run as one or two dimensional Cartesian by restricting the size of the three dimensional mesh. We have written the code to run on the Sparc series of Sun computers and the Cray. For realistic three dimensional calculations, you will need a supercomputer. One and two dimensional calculations can be run on workstations. Parallel versions are being experimented with, currently for the Cray and nCUBE. This code, TOLTEC, is a proprietary product of Amparo, but we do not intend to charge a fee for it. It is export controlled however, so anyone interested in using it has to satisfy and obey certain restrictions dictated to us by DoD. We would very much like to see this code used by researchers in the government, universities, and industry. If qualified users would be interested in further information on TOLTEC or would be interested in beta testing it, please contact me. The kinds of things that it might be particularly useful for are high pressure research where you need to understand the hydrodynamics, anything to do with penetration of solids (for example, trying to design blast resistant or fragment resistant containers, armor/anti-armor, shaped charge jets, etc...), high explosive simulation, shock synthesis of materials, and so forth. We have a very limited staff, so we don't know yet how much support we will be able to offer users of the code, but we will certainly try. Documentation will initially be somewhat sparse, but that will improve into the summer. John -- John K.
