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 or 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
