Windows 2.1.1 Enhancements & Modifications
August 30, 2002
History Analysis Dialog – The Time History Analysis
Dialog now automatically calculates the number of snapshots
that will be generated by a set of input parameters. Further,
the input parameters are verified for consistency before
being sent to the snapshot generation engine and failing
at that point.
Representation of Stiffness Restraint – If a stiffness
is specified at a node, TRIFLEX® Windows now displays
graphical representations at that node indicating both linear
and rotational stiffnesses and the direction or directions
in which they act.
Graphical Display Improved – Occasionally in multiple
runs of reducers or should a reducer follow an anchor, proper
directional characteristics could be hard to ascertain.
The algorithm used to assign a direction to reducers has
been improved. Further output parameter color mapping is
now done on reducers, rather than leaving them with the
default fitting color.
in Line Mode – An inadvertent bug crept into the program
during the previous release that resulted in the failure
of Line Mode graphical representation of the piping system
to display a standard restraint. This problem has been corrected.
Consideration in Input Parameter Color Mapping – Anchors
are no longer considered when mapping input parameters onto
the piping system’s graphical representation. This
will prevent items being found on the input parameter scale
that do not appear in the actual model other than at the
Spreadsheet Node and Component Column Locked – The
left two columns of the output spreadsheet indicating node
number and component type are now locked as the user scrolls
to the left to view additional output data. The locking
allows a continual reference as to the position in the spreadsheet.
Activator Message in Demonstration Versions – A logic
error issued a message indicating that the activator would
have to be removed if the user wished to do calculations
in DEMO mode even if no activator was attached. While the
requirement remains, calculations in DEMO mode require that
no TRIFLEX® Windows activator be attached to the machine,
the message is not issued if there is no activator.
Buttons on Response Spectrum and Time History Dialogs Removed
– The APPLY buttons on the bottom of the Response
Spectrum and Time History property sheet that provided no
useful function were removed.
Element Systems – Systems consisting only of structural
elements no longer cause the program to exit abnormally.
Show Time History Animation Button – The ‘Show
Time History Animation’ button on the Calculation
Output Graphics screen no longer is shown unless Time History
data have been calculated and are ready for display.
Version Number Shown in Output Log – The current TRIFLEX®
Windows version number is now shown as a part of the calculation
output log listing.
Time History Log Format – Output to the Time History
Log has been formatted to add carriage return/line feed
pairs between successive messages, resulting in a more readable
Recalling Data Files from Past Versions – An inadvertent
serialization bug prevented version 2.1.0 of TRIFLEX®
Windows from recalling data files created with versions
1.5.4 and earlier. This error has been corrected.
Inertial Loading Added – Weight loads are now applicable
along any coordinate direction simulating inertial loading
of the piping system.
Wait Cursor Shown During Time History Calculations –
Under some circumstances Time History calculations may take
an appreciable time to complete. A wait cursor is now displayed
during the calculation to alleviate the possible misconception
of a system hang up.
Component Replacement Logic Modified – Components
that are both selected and current may now be replaced without
resulting in abrupt, unexpected program termination, but
the component that replaces the other will no longer be
Restrained Option in B31.4 Code Compliance Now Functional
– The ‘Restrained’ option for B31.4 now
performs as expected.
Time Function Display Scale – The Time Functions Page
Function Display is now scaled properly if small values
are entered in the time/value dialog.
Snapshot Generation Parameter Revision Dialog Indicates
Proper Mode – The Snapshot Generation Parameter Revision
Dialog that is displayed if the ‘Enable Parameter
Revision’ box is selected on the Analysis Tab of the
Time History Analysis Dialog, now display the correct selected
mode when the user initiates a simulation run or modifies
the input parameters.
B31.8 Specified Minimum Yield Strength Report – The
SMYS factor of B31.8 output report was at times incorrectly
stated due to an inconsistency in the association of components
and their node points. A revised algorithm for maintaining
this association will prevent the problem in the future.
Material Database Expanded – The material database
was expanded to include the physical properties and allowable
stresses for Titanium and Inconel Alloy 625.
Case Definition Dialog Modified – It is no longer
possible to specify that a Response Spectrum Analysis or
a Time History Analysis be run in the same case as Mode
Shape and Frequencies.
Response Spectrum Dialog Combined Report Now Default –
In the Response Spectrum Dialog, Spectrum Control Data Tab,
the ‘Combined Report’ check box is now the default
setting and performs as expected.
Expansion Joint Deflections and Rotations Report –
Under some circumstances the selection of Expansion Joint
Deflections and Rotations in the output spreadsheet would
result in an unexpected termination of the program. This
problem has been resolved.
Input Parameter Graphics Dialog Revised – Occasionally
when input graphics are selected the group to be displayed
in the list box can obtain an undefined value. If left unmodified,
a terminal malfunction of the program would occur.
Multiple Restraints Resolved in Output Graphics –
The color mapping algorithm used to render components in
the output graphics display could sometimes become disrupted
if multiple restraints were placed on a given component,
due to a problem in the association of node points and components.
This problem has been corrected.
27. From and To Node Numbers Displayed at Top of Dialog
– The component from and to node numbers are displayed
at the top of component entry dialogs so that the user may
reference them as he traverses the various pages of the
Scanning Components Using Previous and Next Needs No Explicit
Save – The user no longer needs to state whether or
not he wishes to save information that has not actually
changed when scanning through components with the previous
and next buttons.
