Hi
I actually want to measure the pressure at the outlet boundary condition, i have written the following code : DEFINE_PROFILE(outlet_catheter,thread,nv) { face_t f; real NV_VEC (A); T=RP_Get_Real("flow-time"); begin_f_loop(f,thread) { F_AREA (A,f,thread); force+=F_P(f,thread)*NV_MAG(A); PF= force/(15.0*(10^(-4))); } end_f_loop(f,thread) } but it seems that its not calculating the pressure properly, i would appreciate if anyone could kindly help me.. |

you should use other macros. such as DEFINE ADJUST(), DEFINE_EXECUTE_AT_END(),
DEFINE_ON_DEMAND()
