When undertaking Select Link Analysis in Cube Voyager Highway program, it is possible to specify the VOL[#] sub-keyword to reserve the volume set # to store the Select Link volume. Begin by downloading the example ZIP folder.
Care should be taken when setting these additional VOLs and Turns at the same time. Refer to our Reference Guide under Highway Program > Control Statements > TURNS. The manual explicitly reports that:
Also, within the SELECTLINK keyword explanation, the user guide is reporting that with SELECTLINK and the TURNS control statement in the same HIGHWAY program, care must be taken. The example catalog shows this behavior with five simple tests assigning two matrices, therefore with V=VOL+VOL and using a VOL when undertaking SLA. This should clarify how to properly set these statements within your script.
Highway programs #1, #2 and #3 provide the same results and convergence measures (#1=#2=#3):
Highway programs #4 and #5 provide different results and convergence measures than tests #1, #2, #3, but the results and convergence measure are the same between #4 and #5 (#4=#5):
Therefore, if including SLA + VOL the correct implementation is giving in HW program #2, that also includes the TURNS statement T=TURN+TURN, syntax below:
