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!

Re: How to add a fixed force on 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.
