Rachel Brooks,Mark McCormack,Kalwant Bhopals. The technique inherently involves .(..) arithmetic operations, where n is the number of mass points; however, we have reduced it to O[nlog(n)] operations by utilizing a “binning” approach. The algorithm is fully vectorized on the Cray family of supercomputers

Recent modifications in the HOBO mesh,In its original formulation the two-dimensional free-Lagrangian hydro code HOBO used massless tracer points without a mesh. Later we changed to a median mesh with all quantities cell centered. Now we have shifted pressure to the cell vertices resulting in a staggered mesh in velocity and pressure.

India and Israel An Uneasy Embracedirectly from the difference expressions for nodal mass and momentum conservation. The results are multi-dimensional and apply to arbitrarily (as well as regularly) connected grids. In SGH the spatial centering of coordinates and velocity are at nodes while mass, internal energy, and pressure are wi

India and Israel An Uneasy Embracebased on the second order Godunov method. The use of data structure with only one level of indirectness leads to an easily vectorized and parallelized code with a low level of overhead in memory requirement and high computational efficiency. The performance and accuracy of the algorithm has been tes
