Simple steady state initialization of an FMU, together with a re-initialization of the state from the FMU at an event, leading to a nonlinear system of equations over FMUs during initialization
With this test model the following properties are tested:
Defining an FMU with incomplete initialization (so this FMU can only be simulated
if additional initialization conditions are defined in the environment where the FMU
is imported).
In the environment one instance is defined with steady-state initialization.
This FMU leads to a nonlinear algebraic equation over the FMU during initialization.
At an event instant, the internal state is re-initialized from the environment.
