Abstract
We study the features of a new mixed integration scheme dedicated for solving the nonstationary variational problems. The scheme is composed of the FEM approximation with respect to the space variable coupled with a 3-layered time integration scheme with a linearized right-hand side operator. It was applied in solving the Cahn-Hilliard parabolic equation with a nonlinear, fourth-order elliptic part. The second order of the approximation along the time variable was proven. Moreover, the good scalability of the software based on this scheme was confirmed during simulations. We verify the proposed time integration scheme by monitoring the Ginzberg-Landau free energy. The numerical simulations are performed using parallel multifrontal direct solver executed over STAMPEDE Linux cluster. Its scalability was compared to the results of the three direct solvers, including MUMPS, SuperLU and PaSTiX.
