Defining a source term
Hello, :)
I’m trying to create an UDF which define an ultrasonic source term in the momentum equation, and I have the analytical expression of the radiation pressure/ volume :S = a exp(- r2) exp (-x2) ; where “a” is a constant, “ r” is the radial component ant” x” is the axial one. The function must return an x-momentum source term that varies with x and r position The problem here is that the expression is not depending on x-velocity Vx so we can set dS[eqn] to dS/dVx Do you have please any idea about haw can I write this UDF in a different way from that of the UDF manual-section 4.3.15 Thank you, I will be grateful :) |
