Moving heat Source

Can anyone help me in writing a UDF to incorporate a moving heat source. The heat source is Gaussian in nature and when it is stationery, the following UDF works fine. Can anyone tell me how I can move this heat source along the x direction.
Stationery Heat Source UDF: #include "udf.h" #define rb 0.00235 #define f1 0.5 #define Q 1900 DEFINE_PROFILE(gauss_heat_flux,t,i) { real x[ND_ND]; real y,y1; face_t f; begin_f_loop(f,t) { F_CENTROID(x,f,t); y = x[1]; y1=x[0]; F_PROFILE(f,t,i) = (Q/rb*rb)*exp(-(f1*(y*y+y1*y1))/rb*rb); } end_f_loop(f,t) } |

hi,
in the above program can u please explain the function of "i" in line DEFINE_PROFILE(gauss_heat_flux,t,i) and how would you write the same program for moving heat source in 2D? |
