UDF for Electrodynamic force

Elango

Hi everyone,

I need to write a UDF for a 2D body force equation that has to be applied on the blade tip of a turbine.But i am not so familiar with coding so it would be very helpful if you guys could guide me in writing the UDF

F= C1 * exp(-{x - 0.015 - (y - 0.001)]/ y}^2 - c3*(y-0.001)^2)i + c2*exp{-[(x-0.015)/y]^2-c4*(y-0.001)^2}j

i need to represent this body force on the blade tip surface
