1-d and 2-d fluid and MHD codes

A contour plot of a 2-d fluid simulation plot of a jet with a Mach number of 20 entering an ambient pressure-matched region.

Fluid codes simply solve the fluid equations (Eulerian or Lagrangian) on a finite-difference grid. There are other kinds of fluid codes that use finite-element techniques, but I don't know too much about those.

Most of my work has been on radiation hydrodynamics of astrophysical jets, like the one in SS 433 in the W50 Supernova remnant. I am now working on codes to model the high-density Z-pinch experiment at the Plasma Laboratory at the Weizmann Institute.
