C --*** SCANOD *** (BLOT) Scale nodal variable
|
|
C -- Written by Amy Gilkey - revised 04/01/88
|
|
C --
|
|
C --SCANOD reads the values for the nodal variable from the database
|
|
C --and finds the minimum and maximum value.

|
|
C --Parameters:
|
|
C -- A - IN - the dynamic memory base array
|
|
C -- IVAR - IN - the variable index (for GETVAR)
|
|
C -- VAR - SCRATCH - the variable array
|
|
C -- WHOTIM - IN - true iff time step is a whole (versus history) time step
|
|
C -- XN, YN, ZN - IN - the nodal coordinates
|
|
C -- VALMIN, VALMAX - OUT - the minimum and maximum value
|
|
C -- NUMMIN, NUMMAX - OUT - the node number of the minimum and maximum value
|
|
C -- XYZMIN, XYZMAX - OUT - the coordinates of NUMMIN, NUMMAX
|
|
C -- ISTMIN, ISTMAX - OUT - the step number of the minimum and maximum value
