Multiphysics Simulation Software for Your Complex Problems
VSim is a multiphysics simulation tool used by design engineers and research scientists who require precise solutions for challenging problems. VSim’s unique combination of Finite-Difference Time-Domain (FDTD), Particle-in-Cell (PIC), and Charged Fluid (Finite Volume) methods delivers accurate results for a variety of situations.
As a parallel software application, VSim can efficiently handle problems at scale, and simulations run quickly using algorithms designed for high performance computing systems. Trusted by researchers in 30 countries, and used by engineers in industries from aerospace to semiconductor manufacturing, VSim is the ideal multiphysics simulation tool.
VSim Advantages
Powerful and Versatile
VSim uses both finite-difference time-domain (FDTD) and particle-in-cell (PIC) methods to run computationally intensive electromagnetic, electrostatic, and plasma simulations. As a time-domain solver, VSim can perform a full-wave analysis, obtaining the response over a range of frequencies in one run and also provide transient analysis. With the additional PIC algorithms included in VSim, these same simulations can be run in the presence of plasmas and dielectrics, making VSim the complete simulation tool for design engineers in numerous industries.
Accurate and Trusted
With documented accuracy, VSim provides results that users can trust. Created by a team of computational scientists, Tech-X’s code has been cited thousands of times in the scientific literature, and VSim can be found at many of the world’s top research institutions.
Rapid and Scalable
FDTD solvers, such as VSim, are considered the preferred choice for complex problems with a large number of unknowns. With Tech-X’s proprietary cut-cell algorithms, VSim obtains high accuracy without increasing run times. With VSim’s scalable parallel computing capability, very large problems can be solved efficiently on clusters and the largest supercomputers.
