trouble with iterating due to external error-1020
 

Hi,
I interpreted my udf on ansys fluent 14.5 and i didn't have any problem to iterate but suddenly the iteration was stopped and I got this error:

Error: Internal error at line 1020 in file '..\..\src\profile.c'.
Too many profiles
Error Object: #f

my udf consists of several profiles , is this error related to them?
how can I fix it?
Thank you in advance for any help !
