derating and reference density are not taken into account).
Fan Point (blue dot) is the point on the Fan Curve measured under certain normal conditions (i.e.Operating Point (orange dot) is the point showing the actual operating flow rate of the fan based on the pressure difference that it experiences in the system.This curve may also be different if the reference density, if specified for the fan, is different than the density of the fluid that the fan encounters in the simulation. If there is no derating defined for the fan, or it is 1, then it is the same as the fan curve. Operating Curve (light green line) is the derated operational curve that the simulation follows.If you used mass flow rate to define the fan, then the X-axis will be labeled as such. Fan Curve (maroon line) is the defined fan curve in the Engineering Database.It is easily resized by hovering your mouse over one of the four orange edges or corners until the mouse pointer changes, then click and drag.
In the graphics window, a graph will be shown that plots out four different parameters see Image 2 below. Image 1: Show Operating Point post-processing option from the right-click context menu of a defined fan. You can easily access this through a right-click on a specific fan and choosing “Show Operating Point” from the context menu, as shown in Image 1 below.
Since the Flow Simulation 2019 release, there is a new type of plot that you can show to see the operating point for any of the defined fans in a project.
