<p class="MsoNormal"><span lang="EN-US" style="font-family:"Arial",sans-serif">I’m Simulating a Heat pump (TYPE 401) connected to a heat exchanger which is immersed in a heat storage (please see picture enclosed). After some time, the simulation stop because
of the following error :<o:p></o:p></span></p>
