Compatibility with modelica.fluid.machines #1488

Dear AixLib team,

I'm having problems with the integration of modelica.fluid.machines.controlledpump (MSL 4.0) in my AixLib model in Dymola. The model is a heat pump system with two water storages and five m_flow controlled pumps.

The error is grafik

I also tried swapping out individual pumps, which changes the equation but does not resolve the problem of being unable to differentiate the equation: grafik

Therefore I believe that the actual problem lies somewhere else. Are there any experiences concerning the integration of modelica.fluid.machines in AixLib?

Thank you!

Please add a screenshot of your Modelica model
