The potential-flow equation is solved with fixed-value boundary conditions at each end which correspond to a velocity of 1.0 m/s if the cylinder were absent. These conditions are: * patch UPSTRM at LOW boundary, POT= 1.0/1.066 * patch DWNSTRM at HIGH boundary, POT= -1.0/1.066, wherein the 1.066 divisor expresses the ratio of the length of the duct to the distance between the centres of the cells at either end. The velocity components are computed by setting POTVEL=T.
