custom unit model question

[finAtoZ]

Hello all，

I‘m trying to create a new unit model. I find that there is a line that “m.fs.compressor.inlet.flow_mol.fix(1)”. If I want to add new parameter like “m.fs.compressor.inlet.***”, what should I do? A single example would be greatly helpful. Thanks!

@finAtoZ It is not clear from your question exactly what you are trying to do here.

If you are asking about adding additional members to the port (inlet) then the answer is that you cannot do that in the unit model - Port members are defined only by the property package and due to the need to ensure the problem is well-posed you cannot add arbitrary members to a Port.
