Hi,
I am working on blood flow simulation based on CT scan data. I want to know how to write udf for Ansys fluent simulations for pulsatile flow conditions.
Thanks

Hi,
i think you can use transient pulsating in inlet BC or use Transient Table. you can read this thread.

if your condition is periodic/time-dependent then you can go for the transient table. It's lots easier than UDF.
if it depends on some logics/conditions then you can go for UDF.

# include "udf.h" DEFINE_PROFILE (inlet_velocity,thread,time) { real flow_time; face_t f; begin_f_loop(f,thread) { flow_time=CURRENT_TIME; if(flow_time
