### 15.5.25. rmsAve

The `rmsAve` function calculates the RMS average of a variable or expression on the specified location.

- CFX-Solver computes the RMS average of the vertex values for a 3D location.

- CFX-Solver computes the RMS average of the face values for a 2D location. The value for a particular face is computed by arithmetically averaging the vertex values of the face.

    rmsAve(<Variable|Expression>)@<Location>

where:

- `<Variable|Expression>` is a variable or expression.

- `<Location>` is a 2D region or 3D region (such as a domain or subdomain).
