<div class="">Having a look at “machine_magstadyn_a.pro”, I think that the problem may come from SaveSolution. </div>
<div class="">You have: </div>

<div class="">InitSolution takes the data from your res file.</div>
<div class="">SaveSolution saves the current solution, which is not yet computed, thus zero. </div>

<div class="">Can you try by commenting it out: </div>

yes, the discontinuities coincide with the restart: the value of the first point after a restart is not correct for the current.<br class="">
<br class="">
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...)<br class="">
<br class="">
For the restart, I do<br class="">
getdp model1 -restart -solve CoSimulation -bin -v 3<br class="">
(the post-processing is called from the Resolution as it is done in the original machine_magstadyn_a.pro)<br class="">
<br class="">
No point seems to be missing as one can see in the log :<br class="">

<div class="">Hi Joseph, </div>
<div class=""><br class="">
</div>
<div class="">Do the discontinuities coincide with the restart?</div>
<div class="">How are you doing the post-processing for getting the current?</div>
<div class="">Does it behave in the same way if you do post-pro straightaway or just after?</div>
<div class=""><br class="">
</div>
<div class="">I mean</div>
<div class="">getdp xxx.pro -restart -solve xxx -pos xxx</div>
<div class="">OR</div>
<div class="">getdp xxx.pro -restart -solve xxx</div>
<div class="">getdp xxx.pro -pos xxx</div>
<div class=""><br class="">
</div>
<div class="">The behaviour should be the same but it could be that we are missing a time step…</div>
<div class="">I do not use restart often but when I do I take the first option without observing any particular weird behaviour.</div>
<div class=""><br class="">
</div>
<div class="">Best regards, </div>

<p class="">Hello,</p>
<p class="">as one can see on the following picture, I get discontinuities each time I restart my calculations with the -restart option.</p>
<p class="">There is surely something that I miss but I can't find it.</p>
<p class="">Did someone else encouter this problem that could point me to a solution ?</p>
<p class="">Thanks in advance,</p>
