Hi again @dlangner,
concerning the core hours, @AnnaFless can tell you more about the procedure.
And for the use of my core hours - yes! We can do it exactly in the way you mentioned. And you are, of course, still able to post-process the results after you import my finished simulation.
Providing you with my link of your simulation creates a new project in your Dashboard.
Ready when you are 
Best,
Jousef
