Hello
I am having this problem with ansys fluent 15.07. when I tried to read a case and data which was built and run in fluent 14. the following error happened.
Reading "C:\kamyab\from new 32 cpu check\bestfit1-118-754580.dat"...

The fl process could not be started.




the problem is about the UDFs. I have tried these UDFs on fluent 14 and fluent 15.07 in two different occasions.
I have run this case and data in fluent 14 for many many iterations.
I also run this case in fluent 15.07 from the beginning ( I mean init)
so I am sure that UDF are fine.
also I am sure that the problem is with the UDFs. because when I diactiveate them there will be no errors.
please help

its because of double precision. try to run the case with and without double precision.
this took me about 12 days to understand

hi,i worked a lot with fluent 14.5 and 15 but I could not even compile my UDF (actually it is UDRGM) and then shift it to fluent 6.3 and finally could compile my UDRGM with this words:

then I wanted iterate it but I got some error (with double decision running) and then shift it to single decision and again got error and this the massage:

first of all you cannot use case and data of a a newer version of fluent for an older one
secondly, what was ur problem about compiling in fluent 14.5 and 15?

thanks for ur replying
when i work with fluent 14.5 serial it compile my UDRGM but not load it and these are the massages :
Error:
C:\PROGRA~1\ANSYSI~1\v145\fluent\fluent14.5.7\win6 4\3ddp\fl1457s.exe received fatal signal (ACCESS_VIOLATION)
1. Note exact events leading to error.
2. Save case/data under new name.
3. Exit program and restart to continue.
4. Report error to your distributor.
Error Object: #f


but when use parallel version of fluent 14.5 the error for loading is this:

but in fluent 6.3 i compile and load successfully but i can not use my code i mean when i want to start iteration some error appear
