Hello everyone,
I was trying to implement the following UFD into FLUENT to fix uv in RSM,


#include "udf.h"

DEFINE_PROFILE(fixed_uv, t, i)
{
cell_t c;
begin_c_loop (c,t)
{
F_PROFILE(c,t,i) = - 2.*C_MU_T(c,t)/C_R(c,t)* 0.5 * (C_DUDY(c,t)+C_DVDX(c,t));
}
end_c_loop (c,t)
}

however, an error happens when hooking the profile,

Error: CAR: invalid argument [1]: wrong type [not a pair]
Error Object: ()

Please give me some suggestions! Many thanks！
