Open MOdelica Pumping Fluid through Swept volume - modelica

Question

I have the following code, it is throwing errors related to Translation warning. I am using a swept volume to pump fluid from a tank to pipe and to the sink. ANy help would be appreciated.

Answer 1

You have forgotten to set the medium to water in the pressureTransducer (similarly as in all the other components).
I haven't checked with OpenModelica - but at least with Dymola that suffices to make it simulate.
