surface monitor - multiple lines in one chart?
 
Hi, all,

If I monitor a surface in fluent, normally I get one curve in one window. By this means if I had multiple surface to be monitored (separately, not monitor their total intergal or average, etc), I would have several windows clog up on the computer screen, each with only one curve.

This is annoying. Is there anyway I can put those multiple curves in a single window, like the first default one for iteration residuals? Do have have to use user-defined scalars to achieve this?

Many thanks,

jx

Instead of plotting them, you can save monitored data to a text file and then plot them later in the same diagram.

It is very easy: in the 'Define Surface Monitor' window you can select the plot window. Make sure that it says '1' for each monitor, this will ensure that they are all plotted in the same window.

it seems that it can plot two curves in a window, if exceed 2, you can't set 'Define Surface Monitor' to 1 for the third monintoring curve. is that right?

I don't know, but if I try to change the number of the window after having defined monitor, FLUENT automatically sets the number of the window to a new one.

I here confirm what ap said. I am using FLUENT (v6.1.18) on linux. FLEUNT automatically provides me a plot window number for monitoring surfaces (by default a saparately window for each surface monitoring). Sometimes I can reduce the plot window number to a lower value so that more surface monitoring curves can be plotted in a fewer windows. But I could never manage to plot all curves in one window (i.e., residual monitoring in window #0, and all other surface monitoring in window #1). At best, I get two curves in one window, then rest curves in plotting windows with increasing number indexes. In another word, I could not set the plot window (i.e. the index number of the plotting window) to what I want.

Any idea? Thanks,

jx

Interesting... I tested it and you are correct. Fluent does not want them in a single window. Strange.
