C --*** GAUSS *** (DETOUR) Plot element symbols at gauss points
|

C -- Written by Amy Gilkey, revised 03/14/88

C --
|

|
|
C --GAUSS drives the user symbol interface for element variables.
|
||
|
|
C --It processes each element by element block, computing scaling factors
|
||
|
|
C --and element information, then calling the user symbol routine.
|
||
|
|
C --Only elements of selected element blocks are drawn.
|
||
|
|
C --
|
||
|
|
C --Parameters:
|
||
|
|
C -- ISYTYP - IN - the symbol type (as in MODTYP of /DETOPT/)
|
||
|
|
C -- VARFAC - IN - the face variable 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 gauss variables are defined
|
||
|
|
C -- for element block i
|
||
|
|
C -- * - return statement if the cancel function is active
|
||

C --
|
||
|
|
C --Common Variables:
|
||
|
|
C -- Uses NELBLK of /DBNUMS/
|
||
|
|
C -- Uses IS3DIM of /D3NUMS/
|
||
|
|
C -- Uses VECSCL of /ETCOPT/
|

|
|
C -- Uses DTW, VWSCL of /DEVDAT/
