= -1 (minimum):

WN1 = WM1     if   vel_ale_748

WN1 = WM2     if   vel_ale_746

Comments

1.This card is obsolete. It is replaced by /ALE/LINK/VEL.
2.Using Keyword5=«GRNOD» requires a single identifier ID1.
3.Using formulation Iform=0 requires an ordered node list. Using Iform=0 with Keyword5=«GRNOD» also requires an unsortable node group (/GRNOD/NODENS).
