Just having a look at the code in library/FieldUtils/ProcessModules/ProcessIsoContour.cpp - it doesn't look like any 2D functionality exists unfortunately. So perhaps this is the cause of your issue. How big is the file? The contour filter in ParaView should give you a similar result and will work in 2D - though not sure how smooth it would be in comparison. If you use the new high-order vtu format that I believe has been merged in recently - it should all be fairly smooth.

Hi,

I was trying to use the isocontour module of FieldConvert, and first tried a very simple case. When I load the dat file to ParaView using Tecplot Viewer, I get the whole mesh and the fields with it. So, it is not a set of points of the isocontour (should be a set of lines in my case). I also checked the dat file, the first line is Variables = x, y, u, v, p. Is it possible that the module does not work for 2D? The command I am using is:

FieldConvert -v -m isocontour:fieldid=0:fieldvalue=0.0:smooth:globalcondense:removesmallcontour=100 timeSteps/mesh.xml system/session.xml timeSteps/chkFiles/mesh_135.chk/ out.dat

FieldConvert -v -m isocontour:fieldid=0:fieldvalue=0.0 timeSteps/mesh.xml system/session.xml timeSteps/chkFiles/mesh_135.chk/ out.dat

I check the contours from ParaView, and what I am trying to get (u=0 lines) exists. I would be happy if you can help me with this.

PS: On page 121 of the user guide (5.2.0), there is a typo: "5.6.22 Isocontour extraction: iscontour module" (should be isocontour module).

Kind regards,

Ilteber
