While many solvers have been ported to parallel machines, grid generators have left behind. Still the preprocessing step of mesh generation remains a sequential bottleneck in the simulation cycle. That is why the need for developing of stable 3D parallel grid generator is well-justified. Work in this direction is carried out by several institutions <ref>Fraunhofer Institute for Industrial Mathematics, http://www.itwm.fhg.de</ref>. '''parTgen'''<ref>parTgen - partitioner and parallel tetrahedral mesh generator, http://www.itwm.fhg.de/en/hpc__partgen/partgen/</ref> - partitioner and parallel tetrahedral mesh generator is an example of decoupled method developed and implemented by Ivanov et al.<ref>E.G.
