steady state initialization in Modelica

For example, I have a multibody vehicle model with an initial height of, say 0.1 meter (all wheel vertical loads = 0), as the sim runs, the vehicle will drop onto the ground, after 10 seconds, it reaches its steady state.

I wonder if it is possible to initialize the model exactly at the steady state? I read something about the homotopy command, but I was not even sure if it is something that I was looking for due to lack of examples, so I am not able to implement it to my model. I wonder if there are any other solutions to this kind of initialization problem?

Thanks in advance!

Thanks for Matths comments.

  1. The web page matth has provided is very helpful, and if anyone wants to start your simulation from steady state, you should take a look.

  2. I found some details on simulation continuation and more commands from User Manual 1, "Simulator API" section.

Here's one more additional question based on this one,

Is there an equivalent C function in the Dymola/source folder of ImportInitial(), Or ImportInitialResult()? Thanks.
