Plasma Discharge Simulations With VSim

VSimPlasma is a versatile and powerful Particle-In-Cell (PIC) software application specifically optimized for plasma discharge simulation. VSimPlasma explicitly tracks kinetic particle species in arbitrary-pressure background gasses, including the effects of elastic, excitation, and ionization collisions between electrons, ions, and neutral particles.

Using Tech-X’s proprietary cut-cell algorithms, combined with VSim’s unique approach of using both FDTD and PIC methods, VSim quickly and accurately models complex particle dynamics in multiple dimensionalities. Powerful post-processing capabilities allow for robust analysis, and since VSim was designed to run in parallel, it easily installs on high-performance computing systems. Originally created by Tech-X scientists, who continue to be leading contributors to the fields of plasma and computational physics, VSimPlasma is the most comprehensive solution for plasma discharge simulation.

VSim Plasma Discharge case study
" VSim was an essential tool in our modeling of magnetron sputtering. Thanks to the vast array of capabilities available through VSim, we were able to accurately predict the erosion profiles from our current designs, and VSim continues to allow us to optimize our designs for the future. The support staff at Tech-X was also extremely helpful during our initial set-up and modeling process. "
