Hi,
i have a simulation of Ansys CFX 14.5.7 which worked well. Today I wanted to reuse them with Ansys CFX 16.2, but I get a strange error message. Here is the old log file: This run of the CFX-14.5.7 Solver started at 22:51:28 on 15 Apr 2014 by user Frank on ARCHIMEDES (intel_xeon64.sse2_winnt) using the command: "C:\Program Files\ANSYS Inc\v145\CFX\bin\perllib\cfx5solve.pl" -batch -ccl runInput.ccl -fullname "Fluid Flow CFX_001" Setting up CFX Solver run ...

I don't know. 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).

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, |

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 |
