I hadnt seen that the "system.project_solution" considered the unknown name, sorry :-)
Thanks a lot.

Usually a "system.attach_init_function" will make a L2 projection of the initial given function on the system's solution ie. the global variable at first step. But how do you project two different functions on each of the two variables (which supposes taking into account the size of each variable).
