I wonder if it is suitable to directly use C_UDSI_G(c0,t0,0) to calculate the gradient of uds at the boundary since there is no C_UDSI_RG in UDF, or should I use another way? BTW, how does it calculate C_UDSI_G in UDF? I wonder it's calculated by this expression.

I don't find F_UDSI_G in the manual.
