An Ode to CFD
By Steve Bova and Alfred Lorber
University of Texas CFD Laboratory

Old codes never die
They get handed down to you and I

If yours does not have much robosity
You need only add more viscosity

Many a knob and several a switch
Are required to run it without a hitch

If higher flop rates you must realize
Simply generate a larger grid size

If a trivial modification your manager seeks
My estimation is at least ten weeks.
