Double Chenath Simulation crash

Even when the single Chenath simulation can be executed, the double Chenath simulations may still crash as the processes try to read and write into the same files or with large complex assessments. If this occurs, go to Configure|AccuRate Defaults|Simulation Defaults and increase the simulation interval until the double simulations run. By increasing the simulation interval, the two Chenath simulations can avoid writing into the same files at the same time.
