It looks like I had to define my model instance like:
type
ModelInstance* = ref object
....
Run
Then just in the procs `comp:ModelInstance`:
proc fmi2SetupExperiment*(comp: ModelInstance; toleranceDefined:
fmi2Boolean;
tolerance: fmi2Real; startTime: fmi2Real;
stopTimeDefined: fmi2Boolean; stopTime: fmi2Real):
fmi2Status =
Run
seems to keep the same address that is what I was looking for.
