C --*** QEPAIN *** (DETOUR) Paint element contours (quick)
|
|
C -- Written by Amy Gilkey - revised 03/02/88
|
|
C --
|
|
C --EPAINT paints contour sections in a color sequence. Each element
|
|
C --is assigned a single contour value (based on the element variable
|
|
C --value.
|
|
C --
|
|
C --The element block status indicates which element blocks are active
|
|
C --for contours. No contours are drawn in inactive elements.
|
|
C --
|
|
C --Parameters:
|
|
C -- VARFAC - IN - the contour function values
|
|
C -- LENF - IN - the cumulative face counts by element block
|
|
C -- NLNKF - IN - the number of nodes per face
|
|
C -- LINKF - IN - the connectivity for all faces
|
|
C -- HIDEF(i) - IN - true iff face i is hidden (3D only)
|
|
C -- XN, YN, ZN - IN - the nodal coordinates
|
|
C -- ISVOK - IN - ISVOK(i) is true iff the contour variable is defined
|
|
C -- for element block i (always true if nodal variable)
|
|
C -- FMIN, FMAX - IN - the minimum and maximum function value
|
|
C -- * - return statement if the cancel function is active
