Hi All,

I was wondering is it possible to show all residuals rather than the maximum or is it possible to determine which residual is the maximum one?

Thanks

Yup. On Analyze tab (Probe, 2-D, 3-D or Text Output) select 'Restart' as the data source and then 'Pressure Iteration Residual'. It will be most useful in 2-D, probably, since in 3-D you'll only see the values for the iso-surface and not the values for cells internal to the flow.

You can do a 2D or 3D plot of "diagnostics - pressure iteration residual". I'd recommend 2D with "no contour smoothing".
