1) KEYPLOT.DAT FILE: THE FIRST LINE ABOVE (PREPRE_1 and PREPRE_2 READ) OF
THIS FILE GOVERNS 19 PARAMETERS EXPLAINED BELOW:
KEYPLOT,I0SCRN,MVNDX6,NMAT,MN, M,
1 -5 36 20 2194 1097
NMODLSAV, NSECTSAV, NLOADSAV, KGENXYD,NEEDXYD,KDLINED,
1 1 1 500 1000 1000
JERASED,MERASED,JTMOVED,KEYPUSHD,KNODE1, KTRS13,KCYCL
100 600 100 1000 1 0 1
THE DEFAULT VALUES ARE SHOWN ABOVE. THEY ARE MADE TO MEET MOST
USAGE REQUIREMENTS. YOU MAY CHANGE/ADJUST THEM TO SUIT YOUR NEED.
SEE BELOW FOR EXPLANATION OF THESE PARAMETERS:
KEYPLOT: 0 ONLY FIRST 6 PARAMETERS ARE READ,NAMELY, KEYPLOT,I0SCRN,MVNDX6,NMAT,MN,M
KEYPLOT: 1 ADDITIONAL ADJUSTMENT IS MADE, NAMELY ALL ARE READ:
KEYPLOT,I0SCRN,MVNDX6,NMAT,MN, M,
NMODLSAV, NSECTSAV, NLOADSAV, KGENXYD,NEEDXYD,KDLINED,
JERASED,MERASED,JTMOVED,KEYPUSHD,KNODE1,KTRS13,KCYCL
I0SCRN: -5 Reserved for Vendor use
LBAND: 0 Reserved for Vendor use
MVNDX6: NUMBER OF DEGREE WITH KNOWN DISPLACEMENT, MVNDX6 >= 1
NMAT : NUMBER OF MATERIAL PROPERTIES, NMAT = 20 (currently)
MN : NUMBER OF ELEMENTS >= 1
M : NUMBER OF NODES >= 1
NMODLSAV: NUMBER OF MODEL.* BACK-UP FILES TO BE KEPT AFTER SAVE
IN ADDITION TO NEWLY SAVED MODEL.DAT.
BACK-UP FILES ARE TO HELP UNDERSTAND SAVED DATA AND TO
FACILITATE RECOVERY IN THE EVENT THE SAVE MODEL.DAT IS
CORRUPTED OR WRONG. THE LAST SAVED FILE IS ALWAY
MODEL.DAT. ALL SAVED BACK-UP FILES ARE ACCORDING
TO THE SEQUENCE OF SAVING RESPECTIVELY AS MODE.ORI,
MODEL.BK2, ..., MODEL.BK9.
NMODLSAV =1 TO 9, IF = 0, IT WILL BE SET TO 1. MODEL.ORI IS ALWAYS RETAINED.
NSECTSAV: NUMBER OF SECT.* BACK-UP FILES TO BE KEPT AFTER SAVE
NSECTSAV =0 TO 9, IF = 0, NO BACK-UP SECT.* FILE WILL BE RETAINED.
NLOADSAV: NUMBER OF LOAD.* BACK-UP FILES TO BE KEPT AFTER SAVE
NLOADSAV =0 TO 9, IF = 0, NO BACK-UP LOAD.* FILE WILL BE RETAINED.
KGENXYD: NUMBER OF NODES TO BE GENERATED/INCREASED.
NEEDXYD: UMBER OF ELEMENTS TO BE GENERATED/INCRESED.
KDLINED: ABOUT THE SAME AS NEEDXYD.
JERASED: NUMBER OF NODES TO BE ERASED.
MERASED: NUMBER OF ELEMENT TO BE ERASED.
JTMOVED: NUMBER OF TIMES TOTAL TO MOVE A NODE/NODES.
KEYPUSHD: NUMBER OF TIMES PRESS-ONE-KEY BUTTON TO BE PRESSED.
NOTE:
FOR EACH OF MVNDX6,NMAT,MN, M, KGENXYD,NEEDXYD,KDLINED,JERASED,MERASED,JTMOVED,KEYPUSHD:
2) ELEMENT LOCAL COORDINATE SYSTEM IS DEFINED BY THE AID OF KNODE1.
WHEN YOU DO NOT
INPUT THE THIRD NODE FOR ELEMment BEAM, PROGRAM LOOKS FOR THE VALUE OF KNODE1 TO DEFINE LOCAL COORDINATE SYSTEM BELOW.
For most of the big 3-D/2-D structures the Prepre1|Prepre2 can generate
two nodes of elements FAST.
You must at strategic point(s) input the third node. Studying the various options
below, you can properly select the one that is most suitable to a specific task.
KNODE1: -33 ELE LOCAL Z-AXIS SAME DIR. AS GLOBAL Z-AXIS
(MOST ADVISABLE FOR 2-D)
KNODE1: 33 ELEMENT LOCAL Z-AXIS SAME DIRECTION AS Z-AXIS OF
IMMEDIATE ELEMENT AHEAD.
KNODE1: 1 K_NODE IS ALWAYS 1ST NODE OF NODE COORDINATE LIST.
KNODE1: 0 K_NODE IS THE K_NODE OF IMMEDIATE ELEMENT AHEAD.
(FOR 1ST ELEMENT: 1ST NODE OF NODE COORDINATE LIST USED)
KNODE1: 22 ELEMENT LOCAL Y-AXIS SAME DIRECTION AS Y-AXIS OF
IMMEDIATE ELEMENT AHEAD.
KNODE1: 32 ELEMENT LOCAL Z-AXIS SAME DIRECTION AS Y-AXIS OF
IMMEDIATE ELEMENT AHEAD.
KNODE1: 23 ELEMENT LOCAL Y-AXIS SAME DIRECTION AS Z-AXIS OF
IMMEDIATE ELEMENT AHEAD.
KNODE1: -31 ELEMENT LOCAL Z-AXIS SAME DIRECTION AS GLOBAL X-AXIS
KNODE1: -32 ELEMENT LOCAL Z-AXIS SAME DIRECTION AS GLOBAL Y-AXIS
KNODE1: -33 ELE LOCAL Z-AXIS SAME DIR. AS GLOBAL Z-AXIS
(MOST ADVISABLE FOR 2-D)
KNODE1: -21 ELEMENT LOCAL Y-AXIS SAME DIRECTION AS GLOBAL X-AXIS
KNODE1: -22 ELEMENT LOCAL Y-AXIS SAME DIRECTION AS GLOBAL Y-AXIS
KNODE1: -23 ELEMENT LOCAL Y-AXIS SAME DIRECTION AS GLOBAL Z-AXIS
3) OTHER PARAMETERS
KTRS13: 1 FIRST TRUSS ELEMENT TO BE 3-NODE ELEMENT.
KTRS13: 0 FIRST TRUSS ELEMENT TO BE 2-NODE ELEMENT.
KCYCL : 2 TWO CYCLE SEARCH WITH ELEMENT RBAR/BBAR SEARCH FIRST
(AUTOMATICALLY DISABLEED FOR USPPLOT)
KCYCL : 1 ONE CYCLE SEARCH
