Can I change the fundamental model sampling time of 0.00025 s?
Enginuity should not be executed at any sampling rate other than 0.00025 s. In order to produce stable solutions of the gas flow equations under all engine operating conditions, Enginuity models must execute at a sampling rate of 250 microseconds. If the computational power of the hardware is insufficient to compute a full Enginuity step within 250 microseconds then this hardware is inappropriate for Enginuity real time model applications (on modern HIL systems with 2GHz-2.4GHz dual core processors the computation of a full Enginuity step for a four cylinder model takes anywhere from 50 to 150 microseconds). Note: If Enginuity is combined with computational expensive IO calculations so that the combined turn-around time for Enginuity plus auxiliary computations exceeds 250 microseconds, a larger sampling rate can be applied if the model portion is encapsulated within an iterative loop that executes at an integer multiple of this larger base rate in such a way that each iteration step i
