Hi there,

I've got a problem programming a udf to define a logarithmic velocity profile for a BC. Down here you'll find my udf which works on single mode but i got the following error when trying to interpret my vinlet.c file in fluent.

home/apps/Fluent.Inc/fluent6.3.26/src" -I"/home/apps/Fluent.Inc/fluent6.3.26/cortex/src" -I"/home/apps/Fluent.Inc/fluent6.3.26/client/src" -I"/home/apps/Fluent.Inc/fluent6.3.26/multiport/src" -I. -DUDFCONFIG_H="<udfconfig-host.h>" "/home/jarmengol/vent/vinlet.c"
Error: /home/jarmengol/vent/vinlet.c: line 2: syntax error.)

#include "udf.h"
DEFINE_PROFILE(vinlet, thread, index)
real x[ND_ND];
real z;
face_t f;
begin_f_loop(f, thread)
z = x[2];
F_PROFILE(f, thread, index) = log( z / 0.1 ) * .58 / .41;
end_f_loop(f, thread)

I have also tried with #if RP_NODE loop as in a previous threat but is not working... i got the same error.

Thanks in advance!

Do you interpret the UDF in single mode, save the case file, and then open the case file in parallel mode?

inlet profile, parallel, udf, velocity profile
