How to add a fixed force on momentum equation
 

Hi, Could anyone tell me how to add a force into the momentum equation. what should I do? Please help! Sun

I add a fixed force as follow: PATCH (SOURC1 ,VOLUME,5,10,1,1,5,10,1,10) COVAL (SOURC1 ,U1 , 1.000000E-10, 1.000000E+15)

I want to know if it is right?? Can someone tell me?? Thank you very much!

Could you tell me what the source term is and how to express in the momentum equation?

sorry , i can't input my equation into this form. Because the form don't support the Microsoft Equation . My momentum equation is a standard equation. I only want to add a fixed force(such as F=100N) at the end of the equation.
