Tech-X develops a variety of scientific software, including physics simulation software and high-performance computing in the cloud, and provides expert physics simulation consulting services in plasma physics and electromagnetics, including photonic integrated circuits.
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.
VSim Packages
VSim packages are a field-specific and economical alternative to the full VSim PIC simulation tool.
RSim enables users to set up a simulation for modeling radiation effects via a user-friendly interface.
Users can create a geometry from geometry primitives (spheres, cones, boxes, etc.) and boolean operations (intersections, unions) on primitives, or import a CAD file. After creating or importing a geometry, users can assign materials to the geometry, specify common radiation sources, and formulate tallies (dose, fluence, etc.).
RSim translates the simulation setup into Geant4 input then runs the simulation.
USim is a 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.
USim Packages
Individual USim packages are available for Basic Simulations, Hypersonics, and High Energy Density Plasmas.
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. PSim simulations can run much faster than more explicit methods such as classical all-atom molecular dynamics.
High-performance Computing in the Cloud
Coming soon... LAMMPS, NWChem, and Chemistream
LAMMPS Molecular Dynamics Simulator
Tech-X Corporation is pleased to provide a LAMMPS cloud container in collaboration with UberCloud. LAMMPS (Large-scale Atomic/Molecular Massively Parallel Simulator) has potentials for solid-state materials (metals, semiconductors) and soft matter (biomolecules, polymers) and coarse-grained or mesoscopic systems. It can be used to model atoms or, more generically, as a parallel particle simulator at the atomic, meso, or continuum scale.
NWChem: Open Source High-Performance Computational Chemistry
Tech-X Corporation is pleased to provide an NWChem cloud container in collaboration with UberCloud. NWChem uses both both quantum and classical methods (and combinations thereof). NWChem has been applied to biomolecules, nanostructures, and solidstate structures. The NWChem set of computational chemistry tools can model both ground and excited states, and includes relativistic effects.
Chemistream
Computation plays an important role in materials science, engineering, nanotechnology, pharmaceutical research, and many other research fields. Faster time to market, increased return on investment, and enabling new products are common reasons that computation is used in product development. However, surveys have shown that moderate sized companies are only slowly adopting materials simulations and taking advantage of these potential increases in innovation and productivity.
Improving the adoption of computational chemistry software is addressed by developing a framework to help streamline complex simulation workflows involving one or more of the following: molecular dynamics, quantum chemistry simulations, molecular docking, kinetic monte-carlo, and others. This Chemistream framework is a user-friendly application capable of taking advantage of cloud computing resources. Chemistream uses the sub-package Makalii and combines HPC simulations into industry workflows, using the STREAMM package developed at NREL. Read more about Chemistream.
