[Getdp] still facing discontinuities when using -restart option

yes, the discontinuities coincide with the restart: the value of the
first point after a restart is not correct for the current.
For the simulation, I use a modified version of
machine_magstadyn_a.pro. The current is the current in the circuit
connected to the stator coils (which is in fact another rotor...)
For the restart, I do
getdp model1 -restart -solve CoSimulation -bin -v 3
(the post-processing is called from the Resolution as it is done in the
No point seems to be missing as one can see in the log :
