Initialisation problem

Initialisation problem

Hello

I have program a 3 units liquid-liquid extraction steady state model.

It works fine for one units (with 8 stages), fine in SimulationX for two units (but not in openmodelica) and works with 3 units if I decrease the number of stage from 8 to 3.

It fails to find a correct initializationwith the three units.

What can I do ? Try to make the model transient and run it until steady state ?

Thank for your help

Re: Initialisation problem

Problem solved as I shift to a transient formulation. I just had a C * der ( x) to transport equation and no more initialization problem !
The model converge toward a steady-state !
