Model error - sqrt (2*DP_cd.rho_nom) = sqrt (-6.32246e-005) #24

Hi,

I have been getting this simulation error after I have tried simulating the SQThesisModel in Dymola2015: "Model error - sqrt (2*DP_cd.rho_nom) = sqrt (-6.32246e-005)". Similar sort of errors show up when I tried simulating other models too.

This might be a very minor issue but can someone help me out solving this problem? I am new in this so might be missing very silly issues. Thanks in advance.

Could this be related to Dymola2015? I do not use it, but I heard that some of the initialisation code changed...

enter802 commented 9 years ago

yea I am getting this error from initialization.

jowr commented 9 years ago

I do not use Dymola 2015, but I have heard from many people that they experience problems with that particular version. I hope we can fix that soon, but there is no solution for now.

This should now be solved with the latest release and the use of ExternalMedia instead of Coolprop2Modelica.
