Transient - Setpoint vs. Time

When modeling a Fixed Flow Rate Positive Displacement Compressor with a steady setpoint, it is possible to vary the setpoint over time. This replaces the Speed vs. Time transient as defining both the speed and the setpoint would over constrain the system.

Transient Data

For Setpoint vs. Time, the variation of the setpoint must be directly defined in Transient Data. The selected parameter will be forced to meet this data at each time step of the transient simulation. The resulting speed variation over time will be visible in the output.
