A Lightweight Trilinos Solver Interface for Fortran-Based Multiphysics Applications

Sandia researchers have previously developed a lightweight interface software layer that makes linear solvers from the Sandia Trilinos project accessible to the Fortran-based multiphase flow solver suite named MFIX (https://mfix.netl.doe.gov), originally developed by the National Energy Technology Laboratory (NETL).  Under a current Office of Fossil Energy project named "MFIX-DEM Phi", we are optimizing this interface to improve the time-to-solution for various complex multiphase flow simulations such as fluid phase with multiple distinct particles (Eulerian-Lagrangian approach) and multiple fluid phases (Eulerian-Eulerian approach).  In particular, the goal is to improve time-to-solution for simulations such as that depicted in the accompanying image, which shows first-of-its-kind industrial scale gasifier simulations performed as part of an NETL 2008-2010 INCITE award.  It is anticipated that this software interface will be publicly released in 2016.
