Ani3D-extension of parallel platform INMOST and hydrodynamic applications

Abstract

The paper is devoted to an extension of the parallel platform INMOST by finite element and meshing libraries of the Ani3D software package. The extension allows us to develop parallel finite element solvers of boundary value problems and, in particular, hydrodynamic problems. The Ani3D package allows one to build, refine, locally adapt and improve the quality of tetrahedral meshes, perform finite element discretizations of partial differential equations for various types of finite elements, solve the appearing algebraic systems, and visualize the discrete solutions. The INMOST software platform provides tools for creating and storing distributed general conformal grids with arbitrary polyhedral cells, parallel assembling and parallel solution of arising distributed linear systems. We present the integration of two libraries from Ani3D into INMOST platform and demonstrate the functionality of the joint software on the solution of two model hydrodynamic problems on multiprocessor systems.
