Clicking on the Image below will play a movie of a relativistic shock colliding with a high density blob. Note that the paramesh block structure is also shown. The numerical technique used is a relativistic, Godunov, compressible, hydrodynamics code. The movie is courtesy of Alan Calder (U. of Chicago, ASCI/FLASH center) and the IBEAM team. For information about this calculation, see the IBEAM WEB page.
