Vv. Shuvalov et al., 3D hydrodynamic code SOVA for multimaterial flows, application to Shoemaker-Levy 9 Comet impact problem, INT J IMPAC, 23(1), 1999, pp. 847-858
A totally conservative Eulerian 3D numerical code which conserves mass, mom
entum and energy both in the source and remap steps is developed. Mass, mom
entum and kinetic energy are conserved simultaneously during the remapping.
The use of special form of linear viscosity makes the code more tolerant t
o the time step, leaving the second order of accuracy. Multimaterial flows
including those contaminated by dust particles may be investigated using th
is program. The performance of the code is illustrated by modeling the Shoe
maker-Levy 9 impact against Jupiter. Penetration of nonuniform fragments wi
th complex structure into the Jovian atmosphere is investigated. (C) 1999 E
