ANSYS CFX. Does anyone know how to output RMS residual values from the solver to the output parameters? Like, for example, efficiency or pressure drop of a stage.
I found how to return the value of the maximum residual, but I can`t find the root mean square (RMS residual). Maybe who knows?

Define a CEL expression something like rmsAve(u.residual)@domain, and use that expression as a monitor point and make the monitor point an output parameter.

You might need to select the option to add the residuals to the results file to get access to this.
Opaque and redneck pony like this.
Note: I do not answer CFD questions by PM. CFD questions should be posted on the forum.
