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"... 2 user-defined node memory locations, 252178 nodes, binary.

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.

i have found the problem and it was about my code,accually i have changed the code, these kind of errors are because fluent can not access to the right information to give data / or / code ask for wrong type of data, so it can not give any data to solve the equation. i hope it will help |
