Hi guys,

I need to plot some profile, contours, etc. for a large case (mesh > 20M), it is very slow to do it with paraView GUI, so how can I do it using command line? e.g., plot the velocity profile vs channel height. Tons of thanks in advanced.

Regards,

Hi

I suggest taking a look at the various sampling methods available in foam.

Check out the example sampleDict in the following directory.
applications/utilities/postProcessing/sampling/sample

Hi Goncalo,

Thanks very much for your reply. I prefer do the post-processing after the simulation. I might need to plot some iso-surface contour, it might be hard to do it using sample...

You can sample after the simulation. This is done by calling "sample".

There is an iso surface option in the sampleDict but I must confess I haven't tried it. You can output to VTK format which you can open in paraview.

If you are focussed on using paraview, I suggest using pvbatch. I haven't needed to use it up to now but take a look at
http://www.paraview.org/Wiki/ParaView/Users_Guide/Batch_Processing

You can load a state file and output from there.
