Hi,
I ran into a problem which I can't seem to find a resolution for. I've been running FLUENT on the windows console for a while but began running it on the LINUX environment recently. Now the problem that I am getting is that I can't get my UDF running. It ran on the windows box smoothly but the moment I switched to the LINUX box, it gives me the following error. Error: (The directory is long so I won't copy it)/s1.cpp: line 2: syntax error The udf I coded is extremely short and is the following: #include "udf.h" DEFINE_PROFILE(velocity_profile,t,i) { real x[ND_ND]; real y; face_t f; begin_f_loop(f,t) { F_CENTROID(x,f,t); y = x[1]; if (y<=(0.1*0.035)) F_PROFILE(f,t,i)=1435.750179*y; else F_PROFILE(f,t,i)=(0.01758793970)/y; } end_f_loop(f,t) } I ran it for all my other UDFs that worked in the windows environment and still get the same error that I have a syntax error at the beginning of my code while interpreting in linux. Has anyone experienced it? |

Hello,
Do you have a Compiler in Linux? If you use the same UDF from Windows to Linux, it will not be compatible. I experienced a similar problem but I copied my UDF, opened it in the Linux Compiler/text editor (in my case it was Emacs) then saved the UDF under the same name as a .c file. After this, I set up the simulation, then when it came to interpreting ther UDF, I had no problems. Also make sure there's no extra character appearing in the UDF when you paste it into the Linux compiler. If you see text appearing in the top, delete it and make your UDF start with # include udf.h etc... Hope it helps! Dimo |

Hello,
So far I have succesfully worked in WINDOWS and now I am begining to work in LINUX. I want to interpret this simple code: #include "udf.h" DEFINE_PROPERTY(conductivity,c,t) { real k; if (C_T(c,t) > 848.) k = 90; else k = 180; return k; } I opened this UDF with the text editor “Geany” and I saved it under the same name as a .c file, but when I try to interpret it in Fluent, I have the following error in the first line: cpp -I”/home/isabel/Fluent.Inc/fluent6.3.26/src' -I”home/isabel/Fluent.Inc/fluent6.3.26/cortex/src” -I”home/isabel/Fluent.Inc/fluent6.3.26/client/src” -I” Error: /home/isabel/Escritorio/conveccion6082linux.c: line 1: syntax error. Do you think I need to instale other compiler. Which do you recommend me? |

Using another compiler might not necessary solve the problem. It could be that you have a space or some symbol somewhere in line 1 which gives you this error (in my case it was a square that was appearing when I copied the UDF from Windows to Linux, and I did not notice it until spending a few times the UDF!).
Clear all you don't need from the UDF, start with #include 'udf.h' and make sure there's no space or sign or symbol anywhere that should not be there. It worked for me. I then opened Fluent and immediately interpreted the UDF before setting up the simulation and it worked. I hope it'll be the same for you. Let me know how it goes. Dimo |

I have cleared all I don't need from the UDF. Now my UDF is this:
#include "udf.h" DEFINE_PROPERTY(conductivity,c,t) { real k; if (C_T(c,t) > 848.) k = 90; else k = 180; return k; } and now OpenFOAM gives error in line 2 cpp -I”/home/isabel/Fluent.Inc/fluent6.3.26/src' -I”home/isabel/Fluent.Inc/fluent6.3.26/cortex/src” -I”home/isabel/Fluent.Inc/fluent6.3.26/client/src” -I” Error: /home/isabel/Escritorio/conveccion6082linux.c: line 2: syntax error. |

This is a problem with end of line Windows versus Linux. A simple remedy is to use dos2unix command to transform your text, or use some advanced text editor as Editra. Example:
dos2unix your_program.c Explanation: On Windows any end of line is made by characters CR CL, on Unix, Linux and new Macs the end of line is composed only by CL. Hope this will help, Do |

Thank you very much, DoHander. Now I can succesfully interpret my UDF using dos2unix.
Only one more question. Does anybody know what I have to do to compile my UDFs? In Windows I need a Visual C++ compiler, but in LINUX I do not know what compiler to install. At this moment, If I try to compile a udf, I have the following error: for d in lnx86/[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; \ if [ "" = "1" ]; then \ echo "# using gcc64"; \ make ARCHC=gcc64 -k>makelog 2>&1; \ else \ if [ "" = "1" ]; then \ echo "# using gcc"; \ make ARCHC=gcc -k>makelog 2>&1; \ else \ make -k>makelog 2>&1; \ fi; \ fi;\ cat makelog; \ ) \ done # linking to ../../src/conveccion6082propiedadesvariables.c in lnx86/3d # linking to ../../src/makefile in lnx86/3d # building library in lnx86/3d make[1]: se ingresa al directorio `/home/isabel/Escritorio/z/libudf/lnx86/3d' # Generating udf_names.c because of makefile conveccion6082propiedadesvariables.c make[2]: se ingresa al directorio `/home/isabel/Escritorio/z/libudf/lnx86/3d' make libudf.so "CFLAGS=-fpic -shared -ansi -Wall -m32 -O " "LDFLAGS=-shared -lm -m elf_i386" make[3]: se ingresa al directorio `/home/isabel/Escritorio/z/libudf/lnx86/3d' # Compiling udf_names.o because of udf_names.c cc -fpic -shared -ansi -Wall -m32 -O -I/home/isabel/Escritorio/Fluent.Inc/fluent6.3.26/`expr \`pwd\` : '.*/\(.*\)/[23].*'`/`basename \`pwd\`` -I/home/isabel/Escritorio/Fluent.Inc/fluent6.3.26/src -I/home/isabel/Escritorio/Fluent.Inc/fluent6.3.26/cortex/src -I/home/isabel/Escritorio/Fluent.Inc/fluent6.3.26/client/src -I/home/isabel/Escritorio/Fluent.Inc/fluent6.3.26/tgrid/src -I/home/isabel/Escritorio/Fluent.Inc/fluent6.3.26/multiport/src -I. -c udf_names.c # Compiling conveccion6082propiedadesvariables.o because of conveccion6082propiedadesvariables.c cc -fpic -shared -ansi -Wall -m32 -O -I/home/isabel/Escritorio/Fluent.Inc/fluent6.3.26/`expr \`pwd\` : '.*/\(.*\)/[23].*'`/`basename \`pwd\`` -I/home/isabel/Escritorio/Fluent.Inc/fluent6.3.26/src -I/home/isabel/Escritorio/Fluent.Inc/fluent6.3.26/cortex/src -I/home/isabel/Escritorio/Fluent.Inc/fluent6.3.26/client/src -I/home/isabel/Escritorio/Fluent.Inc/fluent6.3.26/tgrid/src -I/home/isabel/Escritorio/Fluent.Inc/fluent6.3.26/multiport/src -I. -c conveccion6082propiedadesvariables.c conveccion6082propiedadesvariables.c:1: error: expected identifier or ‘(’ before ‘/’ token In file included from /usr/include/stdio.h:75, from /home/isabel/Escritorio/Fluent.Inc/fluent6.3.26/src/global.h:18, from /home/isabel/Escritorio/Fluent.Inc/fluent6.3.26/src/udf.h:23, from conveccion6082propiedadesvariables.c:12: /usr/include/libio.h:332: error: expected specifier-qualifier-list before ‘size_t’ /usr/include/libio.h:364: error: expected declaration specifiers or ‘...’ before ‘size_t’ /usr/include/libio.h:373: error: expected declaration specifiers or ‘...’ before ‘size_t’ /usr/include/libio.h:493: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘_IO_sgetn’ |

You need to install gcc on Linux, this is the standard C compiler on Linux. Fluent will pick this by default.

hello,
1)i compiled the udf locally on linux (super-computer), the solution is converging perfectly till 0.05s (flow-time). after that solution is non-converged. 2)the exact same case is run on windows environment (personal-computer), it is converging perfecting through out the simulation. The different between 1 and 2 is two different computers (but same number of core). Any possible solution? |

Hi,
I am using a UDF code that can successfully work in FLUENT on Windows platform. But now when I try to interpret the same code on Ubuntu version of FLUENT I encounter the following error: sh: /ansys_inc/v182/fluent/contrib/lnamd64/cpp: No such file or directory Error: "/home/lab31/Desktop/pressure_driven_flow/nanofluid/TiO2/NF.c": line 1: syntax error. in my code the first line is #include "udf.h" so I do not think this could be the problem. I am sure there is not any problem with my code since it is very simple. still I cannot find the problem. I really appreciate if anybody code help me with this problem. Thanks. |

Hi, I have solved my above-mentioned problem with UDF, which I did not understand for almost two weeks. The problem was I put the comments in UDF code lines just for ease. and it was not reading the code due to this. Now I have removed and it is working well. I liked to share with all of you, so If anyone comes up with this situation can try this. All the best!
