C --MRKNOD marks the nodes which have the minimum or maximum values
|

|
|
C --Parameters:
|
||
|
|
C -- F - IN - the nodal variable values
|
||
|
|
C -- HIDENP(i) - IN - true iff node i is hidden (3D only)
|
||
|
|
C -- XN, YN, ZN - IN - the nodal coordinates
|
||
|
|
C -- IN2ELB - IN - the element block for each node;
|
||
|
|
C -- <0 if not in any selected element block
|
||
|
|
C -- =0 if in more than one selected element block
|
||
|
|
C -- NMIN, NMAX - IN - the number of variables values matching the
|
||
|
|
C -- minimum and the maximum
|
||
|
|
C -- FMIN, FMAX - IN - the minimum and maximum function values
|
||
|
|
C -- BLKCOL - IN/OUT - the user selected colors of the element blocks.
|
||
|
|
C -- BLKCOL(0) = 1 if the user defined material
|
||
|
|
C -- colors should be used in mesh plots.
|
||
|
|
C -- = -1 if program selected colors should
|
||
|
|
C -- be used.
|
||
|
|
C -- BLKCOL(i) = the user selected color of element
|
||
|
|
C -- block i:
|
||
|
|
C -- -2 - no color selected by user.
|
||
|
|
C -- -1 - black
|
||
|
|
C -- 0 - white
|
||
|
|
C -- 1 - red
|
||
|
|
C -- 2 - green
|
||
|
|
C -- 3 - yellow
|
||
|
|
C -- 4 - blue
|

|
|
C -- 5 - cyan
