The results of direct numeric simulations (DNS) of unstable flows, obtained by program complexes IGLA and MECH based on PIC method. These algorithms are the modification on Harlow particles method. The development of the instability was seen on the following tasks:
1. Spherical shell implosion
2. Investigations of unsteady current progress at the implosion gases boundary with energy release
