    Parallel iterative solver VS1

  • Original language description

    Solver is designed for solving large linear systems, arising from the finite element analysis of elasticity problems with voxel grid, in particular problems of micromechanics using CT scan input data. The voxel structure of such problems enables straightforward discretization by regular structured grids. The code, based on finite element method, is optimized to take advantage of such meshing for performance and parallelization. Both Dirichlet and Neumann boundary conditions can be applied. In the secondcase, the arising singular system are efficiently solved making use of projections. The solver is a part of the finite element system GEM, but can be used independently for voxel based problems with a specific voxel format for the finite element matrices.
