UDF value to large for defined data type
Hi everyone,
I'm new to Fleunt and this is my first time interpreting a UDF. When using the Interpreted UDFs dialogue in Fluent version 14.5 I get the following error: cpp I "/usr/css/apps/ansys_inc/v145/fluent/Fleunt14.5.0/src" ... : Value too large for defined data type cpp: netudf.c: Value too large for defined data type Error: "netudf.c": line 1: syntax error. Anyone know what this means? My UDF, netudf.c, is below: # include "udf.h" DEFINE_PROFILE(ICA,thread,position) { face_t f; real t = CURRENT_TIME; begin_f_loop(f,thread) { F_PROFILE(f,thread,position)=(1/11.716310)*(4.600000/3.8909)*(3.8909(0.0725*cos(2*3.14*(0.9t)/0.9))(0.1920*cos(2*2*3.14*(0.9t)/0.9))(0.4004*cos(2*3*3.14*(0.9t)/0.9))(0.2157*cos(2*4*3.14*(0.9t)/0.9))(0.2692*cos(2*5*3.14*(0.9t)/0.9))(0.0699*cos(2*6*3.14*(0.9t)/0.9))+(0.0607*cos(2*7*3.14*(0.9t)/0.9))+(0.0140*cos(2*8*3.14*(0.9t)/0.9))+(0.0409*cos(2*9*3.14*(0.9t)/0.9))(0.0015*cos(2*10*3.14*(0.9t)/0.9))(0.0193*cos(2*11*3.14*(0.9t)/0.9))(0.0312*cos(2*12*3.14*(0.9t)/0.9))(0.0571*cos(2*13*3.14*(0.9t)/0.9))(0.0205*cos(2*14*3.14*(0.9t)/0.9))(0.0070*cos(2*15*3.14*(0.9t)/0.9))(0.9802*sin(2*3.14*(0.9t)/0.9))(0.5866*sin(2*2*3.14*(0.9t)/0.9))(0.2279*sin(2*3*3.14*(0.9t)/0.9))(0.0648*sin(2*4*3.14*(0.9t)/0.9))+(0.0212*sin(2*5*3.14*(0.9t)/0.9))+(0.2039*sin(2*6*3.14*(0.9t)/0.9))+(0.0433*sin(2*7*3.14*(0.9t)/0.9))+(0.0093*sin(2*8*3.14*(0.9t)/0.9))(0.0109*sin(2*9*3.14*(0.9t)/0.9))(0.0527*sin(2*10*3.14*(0.9t)/0.9))(0.0299*sin(2*11*3.14*(0.9t)/0.9))(0.0355*sin(2*12*3.14*(0.9t)/0.9))(0.0001*sin(2*13*3.14*(0.9t)/0.9))+(0.0283*sin(2*14*3.14*(0.9t)/0.9))+(0.0127*sin(2*15*3.14*(0.9t)/0.9))); } end_f_loop(f,thread) } Thanks for the help, Anna

I have had the same problem and I've solved it by using of dos2unix command. The problem, sometimes, is due to LF and CR special characters misunderstanding between the two O.S. and dos2unix helps to fix it.

Dear Anna,
I have encountered the same error on our system. I also tried to use dos2unix to resolve it, but it didn't work. So far, I suspect that it is related to a) the mounting of the file system that holds my working directory, or b) the Cpreprocessor version used by Fluent. In my case, the file system is a nonunix (Windows), mounted using cifsmount package. Working with Fluent 15 on some older SuSE 11 system, the error does not occur. On our newer Linux OS (SuSE Enterprise ...) the mount options are slightly different (due to the newer cifs package) and the error occurs. So I am convinced at least it has nothing to do with the source code of your UDF. If you have resolved the problem in the meantime, please let me know. Hopefully it will work here, too. :) Many thanks for a brief reply. Jens.
