I would load the def file in CFX-Pre and get it to output a V16 def file. That might fix it. Or you might need to regenerate it by some other method (eg load the cfx file in CFX-Pre, or even regenerate the whole thing in CFX-Pre from the mesh).   February 7, 2016, 10:29 #3 Senior Member   Join Date: Jun 2009 Posts: 1,575 Rep Power: 28 Recent release of ANSYS CFX includes additional support for monitoring expressions and a requirement that monitor point names are unique is enforced. Unfortunately your previous setup contains an boundary named IN, and a monitor point also named IN. Just change the name of one of them, and you should be good to go. As Glenn suggested, just open the definition file in ANSYS CFX-Pre. I think you may get an error message about duplicate names, or unsupported names. You correct it as suggested above, and rewrite the definition file. Hope the above helps,   February 8, 2016, 04:28 #4 Member   Frank Weise Join Date: Mar 2009 Location: Germany Posts: 51 Rep Power: 15 Thanks for your help. After a few tests, I've also found that it was the name of the monitor variable IN. best regards Frank  Thread Tools Search this Thread Show Printable Version Email this Page Search this Thread: Advanced Search Display Modes Linear Mode Switch to Hybrid Mode Switch to Threaded Mode Posting Rules You may not post new threads You may not post replies You may not post attachments You may not edit your posts BB code is On Smilies are On [IMG] code is On HTML code is OffTrackbacks are Off Pingbacks are On Refbacks are On Forum Rules Similar Threads Thread Thread Starter Forum Replies Last Post nguyenthanhctm FLUENT 0 December 19, 2013 08:21 mayank.dce2k7 OpenFOAM Running, Solving & CFD 2 November 19, 2013 05:28 heksel8i FLUENT 3 July 22, 2013 10:28 ivy CFX 4 June 8, 2011 21:01 Purushothama Main CFD Forum 0 November 7, 2010 20:12
