Mass Flow-Weighted Average for Monitors
Discovery generally uses area-weighted averaging for all
results monitors. However, you can use mass flow-weighted averaging instead for the
following results variables:
- Temperature
- Temperature uniformity
- Total pressure
- Pressure drop
Under Simulation Options, on the Simulation tab, click Additional Fluid Flow Options to see the options in the expanded panel. Click Mass flow-weighted average for monitors if you want monitors calculated using mass flow-weighted averaging.
You can select inlets, outlets, fluid-fluid interfaces, or planes crossing the flow region. Mass flow-weighted averaging is also available for surface bodies only in Explore.
An area-weighted average is calculated by integrating the scalar variable times the area divided by the total area over the region.
A mass flow-weighted average is calculated by integrating the scalar variable times mass flow divided by total mass flow over the region.
Note:
- Mass flow-weighted average for monitors is on by default for new simulations. This setting might be off in simulations created in previous versions of Discovery.
- If a mass flow-weighted average monitor is created using a location that includes both a solid and a fluid surface, the monitor value will ignore the solid region and return the mass flow-weighted average for the fluid region only.
