Tcl part of the unit process module. These procedures include compound unit processes and some more convenient versions of the C functions.
proc MarchAlongCMinus { old_first new_first direction } {
Purpose: Generate nodes along a new C- characteristic line.
Input :
old_first : a starting point on an existing C- line
new_first : the starting point on the new C- line
on which the new nodes are to be generated.
direction : up or down
Output :
Returns a list of node indices on the new C- curve.
in the order that they are generated.
proc MarchAlongCPlus { old_first new_first direction } {
Purpose: Generate nodes along a new C+ characteristic line.
Input :
old_first : a starting point on an existing C+ line
new_first : the starting point on the new C+ line
on which the new nodes are to be generated.
direction : up or down
Output :
Returns a list of node indices on the new C+ curve.
in the order that they are generated.
