A Fast Multifrontal Solver for Non-linear Multi-physics Problems

The paper presents a highly optimized implementation of a multifrontal solver for linear systems arising in the FEM simulation of multi-physics problems related to the behaviour of porous media. The solver features a careful preprocessing phase that is crucial to considerably speed up both system assembly and Gaussian elimination. When run on a number of relevant test cases, the proposed solver compares very favourably with both its previous unifrontal counterpart and two general multifrontal solvers well known in the literature.
