Buildings.Fluid.Actuators.BaseClasses.Examples.EqualPercentageDerivativeCheck
Information
This example checks whether the function derivative is implemented correctly. If the derivative implementation is not correct, the model will stop with an assert statement.

| Type | Name | Default | Description |
|---|---|---|---|
| Real | R | 50 | Rangeability |
| Real | delta | 0.01 | Value where transition occurs |
| Real | l | 0.001 | Leakage |
