VSim by Tech-X Corporation

Simulations Empowering Innovation

VSim is designed to run computationally intensive electromagnetic, electrostatic, and plasma simulations in the presence of complex dielectric, magnetic, and metallic shapes.

VSim is a cross-platform, multiphysics, simulation software tool that uses finite difference time domain (FDTD), particle-in-cell (PIC), and charged fluid methods for greater computational accuracy and efficient scalability. VSim uses distributed-memory parallelism that enables users to solve extremely complex problems and simulations run rapidly using algorithms designed for high performance computing systems.
