hi ,anyone could help me with this problem i've got ? i wanna calculate the inner product of velocity vector and temperature gradient in fluent : U.

T

Thanks in Advanced.

You could either use the NV_DOT function or write the equation out yourself:

Code:

C_U(c,t) * C_T_G(c,t)[0] + C_V(c,t) * C_T_G(c,t)[1];

C_U(c,t) is the x-velocity component within a cell and C_T_G(c,t)[0] is the x-component of the cell temperature gradient vector.
