Hello,everyone.
I get the source code of "C_STRAIN_RATE_MAG(c,t)" from file named "mem.h" as follow.But i think for rp_axi,it should be %%%(rp_axi ?(2*SQR(C_V(c,t)/C_AVE_Y(c,t)%%%% instead of
#if RP_2D%%%(rp_axi ?(SQR(C_V(c,t)/C_AVE_Y(c,t)%%%

is it wrong in fluent udf?

#define C_STRAIN_RATE_MAG(c,t)\
sqrt(ND_SUM(ND_DOT(C_DUDX(c,t), C_DUDY(c,t), C_DUDZ(c,t),\
(C_DUDX(c,t) + C_DUDX(c,t)),\
(C_DUDY(c,t) + C_DVDX(c,t)),\
(C_DUDZ(c,t) + C_DWDX(c,t))),\
ND_DOT(C_DVDX(c,t), C_DVDY(c,t), C_DVDZ(c,t),\
(C_DVDX(c,t) + C_DUDY(c,t)),\
(C_DVDY(c,t) + C_DVDY(c,t)),\
(C_DVDZ(c,t) + C_DWDY(c,t))),\
ND_DOT(C_DWDX(c,t), C_DWDY(c,t), C_DWDZ(c,t),\
(C_DWDX(c,t) + C_DUDZ(c,t)),\
(C_DWDY(c,t) + C_DVDZ(c,t)),\
(C_DWDZ(c,t) + C_DWDZ(c,t))))\
+ (rp_axi ? \
(SQR(C_V(c,t)/C_AVE_Y(c,t)) \
+ (sg_swirl ? \
(SQR(C_AVE_Y(c,t))*NV_MAG2(C_STORAGE_R_NV(c,t,SV_O MEGA_G))): \
0.)): \
0.) \
)
#else
#define C_STRAIN_RATE_MAG(c,t)\
sqrt(ND_SUM(ND_DOT(C_DUDX(c,t), C_DUDY(c,t), C_DUDZ(c,t),\
(C_DUDX(c,t) + C_DUDX(c,t)),\
(C_DUDY(c,t) + C_DVDX(c,t)),\
(C_DUDZ(c,t) + C_DWDX(c,t))),\
ND_DOT(C_DVDX(c,t), C_DVDY(c,t), C_DVDZ(c,t),\
(C_DVDX(c,t) + C_DUDY(c,t)),\
(C_DVDY(c,t) + C_DVDY(c,t)),\
(C_DVDZ(c,t) + C_DWDY(c,t))),\
ND_DOT(C_DWDX(c,t), C_DWDY(c,t), C_DWDZ(c,t),\
(C_DWDX(c,t) + C_DUDZ(c,t)),\
(C_DWDY(c,t) + C_DVDZ(c,t)),\
(C_DWDZ(c,t) + C_DWDZ(c,t)))))
