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:

Maybe have you edited .c file by windows and are you running on linux platform?
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.

Have you solved this issue? In some cases... it does not work for me.

[J.Leypoldt]

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 C-preprocessor version used by Fluent.

In my case, the file system is a non-unix (Windows), mounted using cifs-mount 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.

I have the same problem and I don't know what to do

Hello, did anyone find a way to solve this problem?

[bharatr]

Try these cases: 1) run the case in a directory that has the shortest possible path length, least depth in directory recursion and least possible number of non-alphanumeric characters in the path. 2) use the same cpp file that compiles the UDF file outside of Fluent but with the full command that Fluent uses, you may have to copy and modify a bunch of things.

Hello!

I have exactly the same problem with the error below .
Basically i am trying to start a computation via a journal file ,in which i try to interpret a udf. In windows i have no problem with execution but in cluster i get the error below . Is there anyone with a solution?

1. Dos2unix didn't help
2. #define _LARGEFILE_SOURCE 1
#define _LARGEFILE64_SOURCE 1
#define _FILE_OFFSET_BITS 64
#define FILESIZE ((int64_t)NUMINTS * sizeof(int))
didn't help either.

The cpp that distributed with FLUENT is 32bit.
The error shown is typically associated to problems accessing specific directories in the fluent installation.
It is a random failure, based on where Fluent is installed.

You can solve this if you use /usr/bin/cpp instead of the cpp provided with installation, by setting the full path to cpp in GUI or TUI command.
