A parallel transient management of finite element solvers by a GRAFCET based monitor

In order to improve the general performances of the simulation of transient coupled phenomena computed by the finite element method, a monitor has been built to manage parallel independent finite element solvers generated by the expert system : FLUX-EXPERT. The task synchronization is made according to Grafcet theory which allows self adaptive time steps and saves a large memory size in the storage of the matrix. The stability of such a managment has been tested and will be discussed.
