plotting data on a boundary

EmadTandis · October 2, 2011, 11:36

Hello everybody
The case is 2D cavity with one curve boundary.after solving the case, I want to plot pressure on the curve boundary. I dont know how I do it.
Also, how can I sample data on it?
Thanks.

Hi Emad,

I guess you can use probes to specify a collection of points (by coordinates) that will make output for given fields against time. You can then manipulate output to your needs and plot it using some external tool.

For using probes refer to the controlDict of the sloshingTank2D tutorial in interDyMFoam.

Also, in paraFoam, you can deactivate the internal mesh view and activate only the view of the required patch (from the object inspector --> Mesh Parts) then use a filter like Glyph for the field you want to plot.
