| dc.description.abstract | In this work, we study the efficiency of the OpenFOAM-based parall el solver for the heat conduction in electrical power cables. The 2D benchmark problem with three cables is used for our numerical tests. We study and compare the efficiency of conjugate gradient solver with diagonal incomplete Cholesky (DIC) preconditioner and generalized geometric-algebraic multigrid solver (GAMG), which is a vailable in Open-FOAM. The convergence and parallel scalability of the solvers are presented and analyzed. Parallel numerical tests are performed on the cluster of multicore computers. | eng |
