DrumBoiler

[Ref_systems]

Hello, everyone!

I tried to run the drumboiler example from Fluid library changing the medium from StandardWater to R134a_ph, but it doesn`t run.
I duplicated and ran it with water first just to make sure it would work after de duplication (it did work after I added Modelica. on the places it was missing).
When I try with R134a_ph it gives the following message:

[1] 09:06:50 Symbolic Warning
The model contains alias variables with conflicting start and/or nominal values. It is recommended to resolve the conflicts, because otherwise the system could be hard to solve. To print the conflicting alias sets and the chosen candidates please use -d=aliasConflicts.

[2] 09:06:50 Translation Error

There are 1 unassigned equations and 0 potential states.

Most likely related to the other state selection issues we are experiencing (see, e.g., #5459)

Any progress on the subject? Can the nightly build version handle it?
