Satish Guest Posts: n/a	Hi Can any one help me, how to get the second order derivative of velocity and temperature for a cell using UDF ? Like d2u/dx2 Thanks Satish

thomas Guest Posts: n/a	Hi, I would suggest to do as follow: U-velcoity_first_gradient = C_U_G(c,t) C_UDSI(c,t,0) = C_U_G(c,t) U-velocity_second_gradient = C_UDSI_G(c,t) indeed: U-velcoity_first_gradient & U-velocity_second_gradient are arrays! Cheers, thomas
