Experiences with FETI-DP in a Production Level Finite Element Application

Pierson, Kendall H.; Reese, Garth M.; Bhardwaj, Manoj K.; Walsh, Timothy W.; Day, David M.; Reese, Garth M.

We discuss application of the FETI-DP linear solver within the Salinas finite element application. An overview of Salinas and of the FETI-DP solver is presented. We discuss scalability of the software on ASCI-red, Cplant and ASCI-white. Options for solution of the coarse grid problem that results from the FETI problem are evaluated. The finite element software and solver are seen to be numerically and cpu scalable on each of these platforms. In addition, the software is very robust and can be used on a large variety of finite element models.
