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

OLD DONGLES WILL ALSO WORK WITH VERSION 6 PROGRAMS. 3) WINDOWS 95. OUR ADVICE
IS TO UPGRADE TO WINDOWS NT. HOWEVER THE PROGRAMS ARE LIKELY TO RUN IF YOU
HAVE THE RIGHT DRIVERS INSTALLED FOR YOUR GRAPHICS CARD. MACHINES WITH
RELATIVELY OLD CARDS THAT HAVE BEEN UPGRADED FROM WIN 3.11 MAY CAUSE
SIGNIFICANT TROUBLE. WE SIMPLY QUOTE THE STANDARD MICROSOFT ERROR
MESSAGE: ILLEGAL INSTRUCTION XX -
IF THE PROBLEM PERSISTS CONTACT YOUR VENDOR. WHICH SOUNDS AS IF
OCCASIONAL CRASHES ARE TO BE TOLERATED. IF THE PROBLEM HAPPENS TO
BE ERRATIC, DO NOT SPEND TO MUCH TIME ON IT AS IT
MAY WELL BE A HARDWARE-RELATED PROBLEM. KNOWN ERRORS
ARE: EXCEPTION 0E WITH BLUE SCREEN & SYSTEM CRASH,
ILLEGAL INSTRUCTION IN GDI.EXE THE SYSTEM USUALLY
BECOMES UNPREDICTABLE IF ONE OF THESE ERRORS OCCURS. IF YOU REALLY MUST
PERSIST, YOU CAN TRY THE SAFE MODE WHICH IS OBTAINED BY HITTING F8 KEY AT

PROVIDED WITH A LIST OF STORED MODES WHICH COMES ON JUST
BEFORE CHOOSING THE 5) MODENT - GRF-S &
GLOBAL-S SINGLE FRF ANALYSIS
OPTIONS GLOBAL-S AND GRF-S HAVE BEEN WITHDRAWN FROM THE ANALYSIS MENU FOR
THREE GOOD REASONS: (i)
IT IS OUR EXPERIENCE THAT THESE METHODS DO NOT ALWAYS GIVE THE BEST RESULTS
FOR SINGLE FRF ANALYSES, NOT A SURPRISING FINDING IN VIEW OF THE FACT THAT
THEIR FORMULATION IS BASED ON SVD/LEAST-SQUARES INVERSION USING DATA FROM
MULTI-FRFs. (ii) TO OUR KNOWLEDGE, NO
ONE IS USING THESE ALGORITHMS FOR ANALYSING (iii) IT IS STILL
POSSIBLE TO USE THESE ALGORITHMS FOR SINGLE FRFs BY DEFINING A .CRD FILE
CONTAINING ONE FRF FILE ONLY. 6) ANSYS TRANSLATOR A TRANSLATION PROBLEM
OCCURRED WHEN THE ORIGIN WAS NOT USED AS AN ACTIVE NODE IN ANY OF THE
ELEMENTS. NOW CORRECTED AND MESSAGE "RESPONSE AT NODE
.. SET TO ZERO" APPEARS. A SIMILAR ERROR ALSO
OCCURRED WHEN ROTATIONS WERE SAVED IN THE CASE OF BRICK ELEMENTS WITH NO
ROTATIONAL DEGREES OF FREEDOM. NOW CORRECTED. 7) UNIVERSAL FILE TRANSLATOR:
RD_FRF_U.EXE CAN NOW HANDLE UNIVERSAL
FILES WITH UP TO 4096 POINTS. HOWEVER, BECAUSE OF THE 1024 LIMITATION IN
MODENT/SH, UNIVERSAL FILES MUST BE SPLIT IN BLOCKS OF 1024 OR LESS POINTS.
(MODENT/SH CAN READ UNIVERSAL FILES UP TO 2048 POINTS LONG BY DISCARDING
EVERY OTHER POINT). 8) NEW UTILITY PROGRAM:

NOW BE RUN WITH A MEMORY RESIDENT GRAPHICS DRIVER. THE MEMORY RESIDENT
VERSIONS ARE IN SUBDIRECTORY \ICATS\EXEC_R. DEVICE=\ICATS\EXEC_R\MET_SHELL
/I THE REAL ADVANTAGE OF
THIS APPROACH LIES IN THAT THE GRAPHICS DRIVER UNDER DOS5, THIS CAN BE
ACHIEVED BY DEVICEHIGH=\ICATS\EXEC_R\MET_SHELL
/I HOWEVER, IT IS BETTER TO
USE A THIRD PARTY MEMORY MANAGER, SUCH AS QEMM386, WHICH WILL AUTOMATICALLY
INSTALL MET_SHELL IN HIGH MEMORY. ------------------------------------------------------------------------ NO ADDITIONAL CHARGE WILL
BE MADE AS LONG AS PLEASE NOTE THAT A
THIRD-PARTY MEMORY MANAGER (QEMM386 BY QUARTERDECK RECOMMENDED) IS REQUIRED TO RUN THESE PROGRAMS. 2) COSMETIC CHANGE TO
CURSOR. CROSS-HAIR, CHECK OR HAND WHEN PRESSED. 3) MASS-NORMALIZATION OF
REAL UNIVERSAL FILES NOW OK. HOWEVER, THERE ARE DIFFERENCES BETWEEN VISCOUS
DAMPING AND STRUCTURAL DAMPING ANALYSIS METHODS AND A ONE-TO-ONE
CORRESPONDANCE IS NOT POSSIBLE. IF A UNIVERSAL FILE IS
RE-SAVED UNDER MODENT/SH FORMAT, THE NSOL FLAG 4) SOME COSMETIC CHANGES
