Hi, All:
I am running fluent 5/6 on a linux machine. Does any one experience using UDF in fluent simulation on that machine. Which makefile should I get from fluent directory. How to compile it and link to solver. I don't have a problem in running fluent on a Unix machine. Thanks MHW |

you will get two makefiles. your directory structure should look like this in linux
/home/username so place the UDF directory as follows: /home/username/UDF then libudf /home/username/libudf then add lnx86 /home/username/libudf/lnx86 then add src /home/username/libudf/src then in the lnx86 dir /home/username/libudf/lnx86 add 2d 3d 3ddp (this corresponds to 2d 3d and 3d double precision) then in the source directory you place your .c code cp /directory location of fluent/Fluent.Inc/fluent6.1.??/src/makefile.udf /home/username/UDF/libudf/src/makefile cp /directory location of fluent/Fluent.Inc/fluent6.1.??/src/makefile.udf2 cp /home/username/UDF/libudf/Makefile that should do it. Cheers, DH |

ignore the first reply it had an error.
BTW this is all in the UDF manual, which you will need. |

[QUOTE=D Harvey
;113010] cp /directory location of fluent/Fluent.Inc/fluent6.1.??/src/makefile.udf /home/username/UDF/libudf/src/makefile cp /directory location of fluent/Fluent.Inc/fluent6.1.??/src/makefile.udf2 cp /home/username/UDF/libudf/Makefile there should be no 'cp' in the second sentence |

Hi all,
I did write a UDF for inlet velocity of my fluent case, but every time I try to interpreted it in Fluent, it says "Error: /home/mp-current/9-2nd-50-tran/inlet_velocity.c: line 2: syntax error." I will appreciate it if anyone help me in this case. and this my UDF Vleocity profile #include"udf.h" DEFINE_PROFILE(inlet_velocity, thread, position) /* inlet x velocity = name of the x velocity */ { real x[ND_ND]; /* this will hold the position vector */ real z; face_t f; /* f = all the cell faces on the boundary*/ begin_f_loop(f,thread) /* thread = given boundary zone, defined automatically when the UDF is hooked to inlet boundary, the macro begin_f_loop is applied to all the cell faces*/ { F_CENTROID(x, f, thread); /* the coordinates of the face centroid accessed by F_CENTROID */ z= x[1]; F_PROFILE(f, thread, position) = pow((60+z)/60,(1/7))+((50+z)/5); /* return velocity is assigned through F_PROFILE */ } end_f_loop(f, thread) } |
