Is there a way to obtain RMS values for a force monitor?

RobR_CFD · May 14, 2021, 20:59

Hey there all you awesome Fluent Super Users,

I am doing transient simulations of forces on bluff bodies.

Is there a way I can obtain from the run an RMS value of the fluctuating force?

I know there is a way to do time averaging of certain values but not sure of how I would go about setting it up for a force monitor? Do I need to code a UDF? (running 2020R2).

------OR-------

for the level of effort do I just do the RMS in excel?

Cheers

Unless you really really need this on-the-fly, RMS in excel is the way to go.
