Fixing illogical "incompatibility components" error copied from OpenModelica Library - modelica

Question

I am trying to model and replicate the "Open Brayton Power Cycle" from the OpenModelica Library and have come across an error message that makes little sense. The error message is the result of incompatibility between sourceMassflow.mo and CombustionChamber.mo, all taken from the modelica library and connected in the same fashion as the library Brayton example has been done.
This error has occurred after completely replicating the "Brayton Power Cycle - Open" from the modelica library.
This is the error I am receiving. This message almost proves that the two components are compatible with one another however I cannot figure out the reason why they are "not working" together.
[11] 14:18:40 Translation Error
[BraytonCycle_First: 49:3-50:84]: Incompatible components in connect statement: connect(sourceMassFlow1.flange, combustionChamber1.inf)
- sourceMassFlow1.flange has components {C_outflow, Xi_outflow, h_outflow, m_flow, p}
- combustionChamber1.inf has components {C_outflow, Xi_outflow, h_outflow, m_flow, p}
I copied all of the library's component parameters into my model and expected this to solve the issue. Nothing I have done fixes this issue, where it seems that these models would be compatible due to the error message above.
Any help or advice would be greatly appreciated.

Answer 1

This model compiles but has issues with simulation. Maybe you can fix those. I changed all the redeclares to use ThermoPower.Media.* mediums.
