/OPT     OPTIMIZATION CONTROL ROUTINE

ANSYS   MISC    OPT
   *****  OPT IS AN OPTIONAL MODULE FOR USE WITH ANSYS-PC/LINEAR *****
  THIS ANSYS ROUTINE IS A CONTROL ROUTINE WHICH ALLOWS THE USER TO
CYCLE THROUGH A SERIES OF ANSYS ANALYSES, VARYING THE DESIGN PARAMETERS
AND TABULATING THE RESULTS.  THE USER CAN OBTAIN DESIGN SENSITIVITY
COEFFICIENTS AND USE THEM FOR DESIGN MODIFICATION ASSISTANCE.
  THIS ROUTINE CAN ALSO DO A COMPLETE DESIGN OPTIMIZATION BASED ON
USER SUPPLIED DESIGN VARIABLES, STATE VARIABLES, AN OBJECTIVE FUNCTION
AND APPROPRIATE CONSTRAINTS AND TOLERANCES.

OPVAR,NAME,TYPE,MIN,MAX,TOLERANCE

 THESE COMMANDS MUST BE GIVEN TO CLASSIFY THE PARAMETERS AND TO DEFINE
  THE ALLOWABLE RANGE AND CONVERGENCE TOLERANCE.

 NAME       - THE VARIABLE NAME AS DEFINED ON A *SET OR *GET
 TYPE       - NONE (DEFAULT) VARIABLES NOT SPECIFIED ARE OF THIS TYPE
            - DV   A DESIGN VARIABLE
            - SV   STATE VARIABLE    A RESULT FROM THE ANALYSIS (*GET)
            - OBJ  THE OBJECTIVE FUNCTION    THE OBJECTIVE FUNCTION MUST
                    BE A RESULT FROM THE ANALYSIS. IT WILL BE MINIMIZED.
                    ONLY ONE OBJECTIVE FUNCTION IS ALLOWED.
 MIN        - MINIMUM VALUE FOR THIS VARIABLE (SIDE CONSTRAINT)
 MAX        - MAXIMUM VALUE FOR THIS VARIABLE (SIDE CONSTRAINT)
               (IF MIN AND MAX ARE BOTH 0.0, THERE IS NO CONSTRAINT)
TOLERANCE   - THE ACCEPTABLE CHANGE OF THIS PARAMETER AT CONVERGENCE

OPLIST,SET1,SET2 - DISPLAYS THE VALUES OF THE VARIABLES.  NOTE, A
   STATUS COMMAND MAY ALSO BE ISSUED TO DISPLAY VARIOUS

  SET1 - DISPLAY VALUES OF ALL ANALYSIS VARIABLES FROM SET1 (DEFAULTS
  SET2    TO THE CURRENT SET) TO SET2 (DEFAULTS TO SET1).  IF SET1 =
          ALL  DISPLAY FOR ALL SETS.   NOTE, WITH OPRUN LOOPING, THE

          WERE GENERATED.

OPRUN, NOPT, POLD,PRAND,NRAND

  RUN AN OPTIMIZATION ANALYSIS ON THE STRUCTURE WITH A MAXIMUM OF NOPT
LOOPS.  THE OPVAR COMMANDS MUST PRECEED
THE OPRUN COMMAND.
  THE OPTIMIZATION PROCESS BEGINS WITH A RANDOM SAMPLE (INCLUDING THE
INITIAL DESIGN AND 3 (DEFAULT) MORE FROM THE ALLOWABLE DESIGN SPACE.
IT THEN PROCEEDS FROM THE BEST OF THIS SAMPLE IN A DIRECTION HAVING
THE HIGHEST CORRELATION WITH THE OBJECTIVE FUNCTION.
  OPTIMIZATION IS AN ADVANCED ANALYSIS TECHNIQUE AND SHOULD BE APPROACHE
WITH CONSIDERABLE CARE.  EACH STEP IS A COMPLETE RE-ANALYSIS OF THE
SYSTEM, SO COMPUTER TIMES CAN BE EXPECTED TO BE LONG.
 POLD - THE FRACTION OF BEST PREVIOUS SOLUTION USED (0.25 DEFAULT)
 PRAND- THE FRACTION OF RANDOM VARIATION INCLUDED   (0.10 DEFAULT)

OPADD, NRES, NUM1,NUM2, C1,C2

  THIS COMMAND DEFINES A RESULT SET OF PARAMETERS  NUM1  AS THE LINEAR
COMBINATION OF THE SETS  NUM1  AND  NUM2.  THE EQUATION USED IS:

      NRES = C1*(NUM1) + C2*(NUM2)

C1  AND  C2  DEFAULT TO 1.0 IF NOT DEFINED.  NUM1 OR NUM2 (BUT NOT BOTH)
MAY BE 0.0   NRES MAY NOT BE 0   THE MAXIMUM SET ALLOWED IS 50.
  THIS COMMAND MAY BE USED TO TAKE THE DIFFERENCE OF TWO SLIGHTLY
DIFFERENT DESIGNS TO TABULATE THE DESIGN SENSITIVITIES.

ANSYS   HELP
  THE HELP SYSTEM ALLOWS DOCUMENTATION ON ANY COMMAND FROM ANYWHERE
WITHIN THE ANSYS PROGRAM.  THE COMMAND MUST BE IDENTIFIED BY A PATH-
NAME WHERE THE LAST ITEM OF THE NAME IS THE TARGET ITEM.
THE PATHNAME CONSISTS OF THE PHASE OF THE PROGRAM, THE ROUTINE IN THAT
PHASE, THE MODULE IN THAT ROUTINE, AND THE COMMAND IN THAT MODULE.
THE PATHNAME MAY END AT ANY ITEM.  THE GENERAL FORM IS -

    HELP,PHASE,ROUTINE,MODULE,COMMAND

FOR EXAMPLE, DOCUMENTATION ON THE "NGEN" COMMAND IN THE NODE MODULE OF
PREP7 MAY BE OBTAINED FROM ANYWHERE IN THE ANSYS PROGRAM BY -

    HELP,PREP,PRP7,NODE,NGEN

NOTE, FROM WITHIN PREP7 THE SIMPLER  DOCU,NGEN  COMMAND SHOULD BE USED.

ENTER  HELP,LIST    FOR VALID PHASE NAMES FOR THE HELP COMMAND
ENTER  HELP,XXX,LIST  FOR VALID ROUTINE NAMES (WHERE XXX IS PHASE NAME)

            WITH NO PARAMETERS. ENTERING THE COMMAND WILL
            CAUSE THE ACTION TO TAKE PLACE.
