Tech-X Products

Tech-X develops a variety of scientific software, including physics simulation software and high-performance computing libraries.

Simulation and Modeling Tools


VSim is a framework that uses PIC (Particle-in-Cell) methods to model particles, so it allows you to simulate the kinetic behavior of particles as well as electromagnetic phenomena. Because VSim supports massively parallel computing that scales to tens of thousands of processor cores, you are able to model complex geometries and more physical phenomena while still obtaining results within a reasonable amount of elapsed time.

General purpose, high resolution shock capturing methods for fluid plasma modeling. Advanced fluid, plasma and electromagnetic modeling on unstructured meshes. The USimComposer GUI enables simulation validation, execution, and visualization in one application. Read more about USim...


PSim is an object-oriented framework that simulates phase morphologies of dense block copolymers melt systems.

PSim quickly solves the numerical self-consistent field theory (SCFT) equations for modeling copolymers. The SCFT algorithm is rigorous method for coarse-graining models of complex block copolymer mixtures such that sufficient detail is retained to describe the novel morphologies these materials form when they undergo phase segregation. This coarse-graining procedure allows researchers to study block copolymer structure in simulations that can run much faster than more explicit methods such as classical all-atom molecular dynamics.

High-performance Computing Libraries


GPULib Enables users to access high performance computing with minimal modification to their existing programs.

By providing bindings between Interactive Data Language (IDL) and large function libraries, GPULib can accelerate new applications or be incorporated into existing applications with minimal effort. No knowledge of GPU programming or memory management is required.

GPULib is built on top of NVIDIA's Compute Unified Device Architecture (CUDA) platform. CUDA is supported by a wide range of NVIDIA products, including GeForce, Quadro, and Tesla cards. Read more about GPULib...

Coming soon... PTSolve and GELUS


PTSolve is the Tech-X-supported Portable, Extensible Toolkit for Scientific Computation. The PTSolve bundled PETSc package is both easier to install and easier to use than PETSc. Tech-X has packaged PTSolve for Windows, Mac OS X, and Linux platforms with 3 different FORTRAN compilers. PTSolve is supported by Tech-X Corporation. Read more about PTSolve...


GELUS is a library of GPU-accelerated preconditioner methods for the sparse triangular solve family of algorithms that includes incomplete factorization and stationary methods. GELUS substantially accelerates the performance of Krylov Iterative Methods by providing targeted performance improvements in the rate-limiting preconditioner solve. Read more about GELUS...

VSim to Be Used in Groundbreaking "Particle Accelerator-on-a-Chip" Research

An international collaboration, led by Stanford University, and including Tech-X Corporation as a partner, has been awarded $13.5 million by the Gordon and Betty Moore Foundation to take an innovative particle accelerator design dubbed the “accelerator-on-a-chip” and make it into a fully functional and scalable working prototype. This laser-driven particle accelerator could have a major impact on the physics community and science in general by providing new particle and photon sources that are less expensive to build, address current infrastructure challenges, and provide broader access to the scientific community.

Tech-X in Denver Post for Simulating Effect of Radiation on Europa Mission's Surface Dust Mass Analyzer

Dr. Sveta Shasharina, Tech-X Vice President and Principal Investigator for the simulation project to calculate the level and effect of radiation on the Surface Dust Mass Analyzer (SUDA), was interviewed by the Denver Post. Tech-X is assisting NASA with exploration of Europa, one of Jupiter's moons, which scientists think may contain life.
