VSim

VSimColor is a high performance electromagnetic code using the FDTD numerical method and also solves for particle motion and plasma physics kinetic equations.

 

VSim model of potential and dustVSim is a flexible, multiplatform, multiphysics software tool for running computationally intensive electromagnetic, electrostatic, magnetostatic, and plasma simulations in the presence of complex dielectric, magnetic, and metallic shapes. Switch easily between 1, 2 or 3 dimensions, and then watch your model run lightning fast using algorithms designed for the exacting demands of high performance computing systems, whether on your laptop or supercomputing cluster.

VSim can be used to simulate a variety of problems on regular, structured, orthogonal meshes with embedded boundaries (cut cells) for complex geometries, which can be imported from CAD models or constructed in the VSimComposer front end. Easily available Finite-Difference, Time-Domain (FDTD) methods allow rapid integration of the Maxwell equations in full or in approximate forms, such as electrostatics and magnetostatics. Self-consistent solutions in the presence of charged particles can be carried out using particle-in-cell methods and/or charge fluid methods. Post processing can be carried out using the built on analyzers, or users may write their own for easy incorporation into the VSim framework.

The advanced packages [Electromagnetics (EM), Microwave Devices (MD), Plasma Acceleration (PA), Plasma Discharges (PD), Semiconductor Devices (SD)] bring in the special capabilities needed for those application areas. These include high-order methods, cut cells, electron emission, both primary and secondary, dispersion control, sputtering, collisions, field ionization, and quasiparticle propagation. In combination, all packages provide a powerful tool covering a wide range of physics.

VSim with its packages can be used for everything from education about fundamental processes to advanced simulations of systems with complex shapes. All packages come with rich sets of examples to assist in initial usage. VSim easily installs and runs on the variety of systems available to students, including Windows, Mac OS X, and Linux platforms.

 

From the World's Largest Supercomputing Facilities to You

In the early years of its development, VSim's physics engine was used to meet the needs of a variety of challenges for the United States government, including plasma acceleration, accelerator cavity modeling, and magnetic fusion studies. These challenging studies required thousands of processors at the nation's largest unclassified computing facilities.  Now you can perform the same simulation modeling on your workstation or cluster.

 Scalable Simulations

Since VSim supports massively parallel computing and scales to tens of thousands of processor cores, new problems that were previously unsolvable are now within reach. VSim works on Linux, Windows, or Mac OS X platforms. Our competitive pricing means that the more computing cores you need, the less you pay, whether you use batch computing on clusters, or large single computing jobs.
