= 0 (linear):

W N 1 = W M 1 + ( W M2 − W M 1 ) 1 N + 1

= 1 (maximum):

WN1 = WM1 if |WM1| > |WM2|

WN1 = WM2 if |WM1| < |WM2|

= -1 (minimum):

WN1 = WM1 if |WM1| < |WM2|

WN1 = WM2 if |WM1| > |WM2|

  
Keyword5 «GRNOD» or «NODES» defines the way of providing secondary nodes  
M1 First mainr node number  
M2 Second main node number  
IDi Secondary nodes identifiers or node group identifier (depending on Keyword5). 2  

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 This card is obsolete.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).
