is a fluid plasma modeling framework that simulates the dynamics of charged fluids or neutrals.
Using structured or unstructured meshes, USim quickly and accurately solves such basic problems as shock and instability capturing in inviscid, compressible neutral gas flows (Euler equations) or profile evolution in ionized plasmas (ideal MHD equations).
Advanced USim packages also support increasingly complex fluid models such as Hall MHD, two-fluid plasma, and Navier-Stokes enabling increasingly detailed models of hypersonic flows and improved designs for high energy density laboratory plasma experiments. USim's built-in three-dimensional visualization capability, multi-platform availability (Linux, Mac, and Windows), and examples will get you up and running quickly.
Examples and documentation for each USim physics and algorithm option reduce your learning curve and ensure faster results.
