Dear everybody,

for a project we are trying to incorporate a model of a hydraulic element into a larger simulation.
The rest of the model was developed with a different software, which is unfortunately not able to cover the hydraulic behavior and just the mechanics of the remaining system.
What we are trying to do is use the c-code generate by OpenModelica and combine it with the integrator of the of the software in order to run it as a single, rather than a co-simulation of the components.
The problem with the other software is that it can't solve the differentials in our hydraulic element.
So we basically want the use the c-code from modelica to solve the for the Jacobian and then let the integrator of the other software solve for the next time-step.

Has anyone ever tried something similar?
How can I combine the c-code with a different integrator, which libraries and parts of the solver from OpenModelica  would I need to use?
Or can anyone tell me where in the code OpenModelica starts it's own integrator, i.e. where I'd need to alter the code to feed the data to a different integrator?

Thanks,

Fynn
