UDF about transient case
Hi! This is my first time to use UDF. I want to define the inlet velocity as v=v0*sin(2*pi*f*t)in 3d tube. I read the fluent documentation (4.3.12 DEFINE_PROFILE). But the example is steady state. I confused how to add the time variable in my DEFINE_PROFILE macros.
Thanks in advance!! |
Re: UDF about transient case
How about something like that?
#include "udf.h" DEFINE_PROFILE(unsteady_velocity, thread, position) { face_t f; begin_f_loop(f, thread) { real t = RP_Get_Real("flow-time"); F_PROFILE(f, thread, position) = v0*sin(2*pi*f*t); } end_f_loop(f, thread) } Have fun MATEUS |
