VSim is a cross-platform computational framework for multiphysics, compatible with Windows, Linux, and macOS.
It includes VSimComposer, a GUI for visual setup of simulations, supporting CAD geometry import and direct geometry construction. VSimComposer allows users to execute data analysis scripts and visualize results in one, two, or three dimensions. VSim utilizes the Vorpal computational engine, which has been applied to simulate electromagnetic systems, plasmas, and rarefied as well as dense gases. VSim is used for modeling basic electromagnetics and plasma physics, complex metallic and dielectric shapes, photonics, vacuum electronics including multipactor effects, laser wake-field acceleration, plasma thrusters, and fusion plasmas.
The Vorpal computational engine is a versatile simulation tool designed to operate across one, two, or three-dimensional spaces. It supports various computational modes, such as the full electromagnetic mode, where it utilizes the Finite-Difference Time-Domain (FDTD ) algorithm, and can also work with electrostatic or magnetostatic fields.
Particles within Vorpal, whether charged or neutral, can be modeled as a fluid or kinetically using the Particle-in-Cell ( PIC ) algorithm. The engine ensures these particles interact self-consistently with fields. It can also simulate the interaction of particles and fields with a variety of structures, including conductors, particle absorbers, reflectors, and others, using cut-cell techniques to maintain accuracy.
The computational domain in Vorpal offers flexibility with boundary conditions, supporting periodic domains or boundaries that can simulate an infinite space using Perfectly Matched Layers (PML) or other types of outgoing wave boundary conditions. The output data from Vorpal is in the Hierarchical Data Format (HDF5) and is compliant with VizSchema standards, facilitating further analysis and visualization.
