Webffddm. In the acronym ffddm, ff stands for FreeFEM and ddm for domain decomposition methods. The idea behind ffddm is to simplify the use of parallel solvers in FreeFEM: distributed direct methods and domain decomposition methods. Parallelism is an important issue because, since about 2004, the clock speed of cores stagnates at 2-3 GHz. WebDistributed Linear Algebra. For a given finite element space V h V h, the domain decomposition induces a natural decomposition of the set of the global degrees of freedom (d.o.f.) of V h V h into the N N subsets of d.o.f.’s (N i)N i=1 ( N i) i = 1 N each associated with the local finite element space V hi V h i . We have thus. fish of thieves fabricWebFreeFEM is interfaced with PETSc and SLEPc which offer a wide range of sequential or parallel linear or nonlinear solvers, time steppers, optimizers, and eigensolvers. In particular, it gives access transparently (without much changes to user code) to: distributed and multithreaded direct solvers ( PARDISO, MUMPS, SuperLU ), multigrid solvers ... fish of the week fws
