UNSTRUCTURED PRISMATIC DISCRETIZATION OF COMPLEX GEOLOGICAL STRUCTURES IN THE PARALLEL MODE

M. L. Sidorov, V. A. Pronin
VANT. Ser.: Mat. Mod. Fiz. Proc 2015. Вып.1. С. 47-55.

The paper presents a parallel grid generation method for prismatic unstructured grids used for the discretization of complex geological structures in oil and hydroecology simulations. The method enables grid matching to various types of objects (complex-trajectory wells, geological fractures, reservoirs etc.) and offers high grid generation speed. The method is implemented in the NIMFA code.

Keywords: thermohydrodynamic simulator, unstructured grid, parallel grid generator, matching, frontal method of spheres, generalized angular point method, geological structures, NIMFA code, MPI paralleling.
