HELP!!!about species transfer
now I am using species transfer. but there are a problem with it. the mass fraction is suppose to smaller than 0.5,but the running result is always bigger than 0.5. I try to write UDF to fix the value. but fluent always show me mistake. I hope anyone can give me a help for this problem.
Thanks very much. #include "udf.h" DEFINE_PROFILE(mass_fraction, thread, position) { real y; face_t f; Thread *t; cell_t c; int i; y = C_YI(c,t,i); if (y < 0.5) y = y; if (y>0.5) y = 0.5; begin_f_loop(f, thread) { F_PROFILE(f, thread, position) = y; } end_f_loop(f, thread) } |
