Hi Ilteber, 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. Not sure if you're aware but you can also use the tag fieldstr="u" rather than fieldid - just a bit more explicit than using the index. Kind Regards, James. ________________________________ From: nektar-users-bounces@imperial.ac.uk <nektar-users-bounces@imperial.ac.uk> on behalf of İlteber Özdemir <rilteber@gmail.com> Sent: 18 October 2022 21:43 To: nektar-users <nektar-users@imperial.ac.uk> Subject: [Nektar-users] isocontour Module This email from rilteber@gmail.com originates from outside Imperial.
