A broad class of problems in plasma physics can only be treated by solving the full kinetic problem. Such problems can be addressed either through particle based codes, i.e. Monte-Carlo techniques, or by directly solving Vlasov's equation. The latter approach is the preferred technique for just one spatial dimension but due to the massive memory requirements is usually replaced by a MC model in higher dimensions. At Warwick both techniques are used and continually developed. These are used to address problems in the solar wind and magnetosphere as well as fundemental plasma physics problems such as non-linear Landua demping, IAT and BGK modes.
For PIC simulations Warwick, along with Imperial and Oxford, is developing the EPOCH code. This is freely available to UK based researchers and details can be found on
