Hi! everybody, I meet a question when using udf function of Fluent, my machine is unix system and IBM workstation.when I load library file appear error "open_udf_library:No such file or directory". But I am success in PC win2000 system. Please give me a way to solve it, Thanks very much.

the question furture description:

1) the information in the file /scratch/wqgong/ufd/log produced when compile is

for d in aix51_64/[23]*; do ( cd $d; for f in ../../src/*.[ch] ../../src/makefile; do if [ ! -f `basename $f` ]; then echo "# linking to" $f "in" $d; ln -s $f .; fi; done; echo ""; echo "# building library in" $d; make -k>makelog 2>&1; cat makelog; ) done # linking to ../../src/wall_pressure_2D.c in aix51_64/2d # linking to ../../src/makefile in aix51_64/2d

# building library in aix51_64/2d

2) the error information in the file /scratch/wqgong/ufd/libudf/aix51_64/2d/makelog is

# Generating udf_names.c because of makefile wall_pressure_2D.c

It doesn't look like you have a c compiler installed.

The bit where it says "/bin/sh: cc: not found" is the important bit.

Thanks Rob's help very much, but my manchine is installed a c complier at /usr/vac/bin. I want to know how to do for me?

Thank you very much, According to your advice I solved my problem by placing the C complier location directory in the .cshrc file.

Hi Gong!

I have posted a message (seehttp://www.cfd-online.com/Forum/fluent.cgi?read=21676) similar to your message, but there isn't this part "/bin/sh: cc: not found"... ???

Could you explain how have you solved your problem going into detail?

Thanks

Tim

Hi!, Tim, I think maybe your issue is different from mine, my question just is the C complier executable file path not connected, but I still hope have a help. I put the path into the file ".cshrc ". the detail step is:

1)after % in unix, input the commond: vi .cshrc open the file .cshrc

2) then add the following path in this file:

set path = ( /usr/vac/bin )

then use flunet udf funtion again, all is ok.

Hi Gong!!!

Thank you for your fast reply!!! I've finally found my stupid mistake:

I 've created 3d directory in libudf, while my mesh was 2d !!!I hope this could be useful for someone else.
