WELCOME TO VERSION 2008B ! ! ! ! ============================================================ 10 May 2008 = 1) GENERAL -A NEW SET OF TRAINING VIDEOS
HAS BEEN RELEASED IN\ICATS\VIDEOS. -THE MENUS FOR ALL PROGRAMS
HAVE BEEN MADE CONSISTENT AND SEVERAL ITEMS HAVE BEEN RE-GROUPED. -THE PROGRAMS CAN BE RUN VIA
ANY OF THE FOUR METHODS From ICATS Main Panel
(Revised & Extended) By double-clicking on a
data file By selecting an analysis
type from Main Panel By using a batch file
script, or as a command from the command line -IF RUN FROM THE COMMAND
LINE, THE FORMAT IS "PROGRAM_NAME DATA_FILE
ANALYSIS_OPTION" EG "MODENT XYZ.PRJ
3" 2) DATA FILES - THE INDIVIDUAL DATA FILE
FORMATS REMAIN UNCHANGED (SINCE 1985!) - HOWEVER, THE FUNCTIONALITY
OF THE .PRJ FILE EXTENDED BY THE POSSIBILITY OF
ADDING .EIG & .TIM FILES. - NEW UTILITY PROGRAM
MAKE_PRJ WILL CREATE A .PRJ FILE BY SIMPLY BROWSING THROUGH
EXISTING FILES. - BECAUSE OF ITS EXTENDED
FUNCTIONALITY, MANY OPTIONS IN MODENT, MODESH, MODPLAN AND MESHGEN WILL NOW REQUIRE
THE USER TO OPEN A .PRJ FILE, RATHER
THAN OPENING TWO FILES, SAY .DSP & .EIG, IN SUCCESSION. 3) THE DRIVER PROGRAM, ICATS.EXE, HAS BEEN RE-WRITTEN - THE USER CAN LAUNCH THE
PROGRAMS EITHER ON A NAME BASIS, OR ON AN ANALYSIS OPTION
BASIS. - THE LATTER PROVIDES THE
POSSIBILITY OF (i) SEEING WHICH DATA FILES MIGHT BE NEEDED (ii) CREATING THESE DATA
FILES 4) MODENT CHANGES - NEW FREQUENCY-DOMAIN
OPERATIONAL MODAL ANALYSIS OPTION IN MODENT. IT IS NOW POSSIBLE TO
ANALYSE GENERAL RESPONSE (IE NOT FRF) MEASUREMENTS IN THE SAME
WAY AS FRF MEASUREMENTS. - CO-ORDINATE MIS-LABELLING
IN .EIG FILE AFTER MODAL ANALYSIS HAS BEEN FIXED. - THE - THE AUTO-RESONANCE
DETECTION IN SIMO MIFS HAS BEEN ENHANCED. - GENERATE FRF OPTION MENUS
HAVE BEEN REVISED. FRF PLOT CONTROL COMMANDS HAVE BEEN
TRANSFERRED TO THE GENERATE FRF MENU FROM THE OPENING MENU. 5) MODESH CHANGES - THE GUIS FOR OVERLAY,
ANIMATE & COMPARE OPTIONS HAVE BEEN REVISED EXTENSIVELY. - THE MAC CORRELATION CAN BE
DONE BETWEEN FOR DIFFERENT MODE RANGES FOR SETS 1 AND 2. - THE NEXT/PREVIOUS/MODE
NUMBER COMMANDS HAVE BEEN REMOVED FROM THE THE USER NEEDS TO CLICK. - "LIST
MODIFICATIONS" OPTION ADDED TO MODIFY. 6) MODPLAN CHANGES - DATA INPUT IS NOW A .PRJ FILE, RATHER THAN .DSP, FOLLOWED BY .EIG. - THE GUI HAS BEEN REVISED
EXTENSIVELY - NEW FAST CO-ORDINATE SELECTION ALGORITHM HAS
BEEN ADDED (OPTISET) - NEW FACILITY TO REMOVE
& DISPLAY INTERNAL NODES HAS BEEN ADDED 7) MESHGEN CHANGES - THE GENERAL GUI STRUCTURE
HAS BEEN MODOFIED TO MAKE MESHGEN CONSISTENT WITH THE OTHER PROGRAMS. - THE GUI FOR .EIG TRANSFORM
HAS BEEN RE-WRITTEN WITH MANY NEW FEATURES. IT IS NOW POSSIBLE TO
SELECT ANY NODE FOR TRANSFORMATION, RATHER THAN HAVING TO TRANSFORM THEM
SEQUENTIALLY. - THE USER'S GUIDE HAS BEEN
EXTENSIVELY REVISED AN RE-ORGANIZED. 8) NEW UTILITY PROGRAMS - FOUR NEW UTILITY PROGRAMS
HAVE BEEN ADDED TO THE MODENT SUITE. MAKE_PRJ IS A GUI TO
EDIT/CREATE .PRJ FILES. MAKE_FRC IS A GUI TO
EDIT/CREATE EXTERNAL FORCE (.FRC) FILES. MAKE_MOD IS A GUI TO
EDIT/CREATE .MOD FILES. MAKE_CMD IS A GUI TO CREATE
COMBINED MODAL DATA (.CMD) FILES - LISTFRF HAS BEEN REVISED
AND RENAMED MAKE_CRD. ============================================================ ! ! ! !

NODES CORRECTLY. RESULTS NOT
AFFECTED. 5) MODESH. IT IS
NOW POSSIBLE TO ANIMATE MODELS WITH MISSING DATA BY IGNORING THE
MISSING DATA, EG ELEMENTS WITH UNDEFINED NODES 6) MODESH. THE
COMPARE OPTION HAS BEEN ENHANCED BY BETTER MODE SHAPE CORRELATION. THE 4-PLOT FORMAT HAS
BEEN REPLACED BY A SINGLE PLOT, UNDER WHICH THE BEST/WORST 20 CORRELATION
CO-ORDINATES ARE LISTED. THE RANKING IS THE DISTANCE TO THE LEAST-SQUARES FIT
LINE. 7) MODESH. A PLOT
SCALING PROBLEM WHICH AFFECTED THE MODIFY OPTION HAS BEEN FIXED.
THE PROBLEM OCCURRED FOR VERY LARGE CIVIL ENGINEERING STRUCTURES WHOSE 8) MODESH, MESHGEN
& MODPLAN, CAN NOW DEAL WITH UP TO 750,000 NODES AND 1,500,000
