Hello
I am trying to call an external C function which will generate unique key (for shared memory) at the start of simulation and then save it into a variable which will be accesible from submodels in my scheme. But I cant to find a way to call the function only one time at the start of simulation(when {time== 0 didnt work}) and then how to set it as global variable so other submodels can acces it. Thanks for reply:)
