    <div class="moz-cite-prefix">For the restarts, I don't do a
      SaveSolution after the InitSolution.<br>
      <br>
      My simulation is inspired by the HeatReservoir example on the old
      wiki.<br>
      I use the same principle: a bash script exchanging data with getdp
      through a .pro file and restarting the simulation as needed.<br>
      <br>
      By mimicking the example, I'd  modified the file
      machine_magstadyn_a.pro like this for the restart:<br>
      <br>
          Operation {<br>
            If(par_batch==0) // start of the simulation<br>
             ...<br>
            Else             // restarts<br>
             InitSolution[A];<br>
             //ReadSolution[A]; // redundant => warnings "Prematured
      end of file"<br>
      <br>
             InitSolution[M];<br>
             //ReadSolution[M]; // redundant => warnings "Prematured
      end of file"<br>
      <br>
             InitSolution[T];<br>
             //ReadSolution[T]; // redundant => warnings "Prematured
      end of file"<br>
      <br>
             ...<br>
            EndIf // If(par_batch==0)<br>
            <br>
            ...<br>
      <br>
      As in the example, for the restarts, I was also calling
      ReadSolution (which caused problems) until Christophe has shown me
      that it was not necessary.<br>
      <br>
      I have only discontinuities for the system A (electromagnetical
      one) but not for de Mechanical one and not for the Thermal one.<br>
