Windows 2.1.0 Enhancements & Modifications
23 July 2002
Spectrum Analysis -- TRIFLEX® Windows now has the ability
perform analyses based on defined vibration spectra, adding
the loading so induced into the occasional load considered
for one or more case definitions. As a byproduct of this
addition, the ability to store, recall, and edit specific
spectral definitions was included, as well as the ability
to view the spectrum graphically.
History Analysis -- TRIFLEX® Windows dynamic capability
has been enhanced with the ability to specify user defined
or preprogrammed time dependent forcing or displacement
functions at selected nodes of the piping system. The effect
of the time variant function on the displacement of the
system may then be shown graphically in an animation sequence.
The loading so imposed has an effect on the system displacement,
forces, moments, and stresses, which may be viewed on a
spreadsheet at each time increment. The maximum of these
system effects can be added onto the occasional loading
for one or more case definitions.
Hammer System Reactions -- Water hammer analysis has been
added to TRIFLEX® Windows, automatically calculating
the system response to rapidly changing incompressible fluid
flow conditions. Working through the Time History mechanism,
this feature calculates the forcing functions at the piping
system nodes along with their time of arrival, allowing
the user to simulate a water hammer event.
Parameter Graphic Display -- Several of the parameters assigned
to a component of the piping system during input including
pipe sizes and properties, insulation characteristics, operating
and design pressures and temperatures, wind and soil loading
details, and allowable stresses, may be mapped onto the
piping system as a set of predefined colors. In addition,
the function of the graphic scale has been updated to translate
the color code back into text.
Progress Log Control – The display of the calculation
progress log can now be controlled from a dialog brought
up with the CALCULATE / PROGRESS LOG PREFERENCES menu item,
allowing the user to clear the log after each run or on
demand and specifying whether a full, summary, or acknowledgement
report is displayed during the calculation. The error message
text for several error conditions occurring in the calculator
routines, PREPRO.EXE and TFSD.EXE were modified such that
they could be recognized while displaying a summary report.
1. Printing of the Progress Log is now functional –
Using the FILE / PRINT or FILE / PRINT PREVIEW menu selections
now works properly when the Calculation Progress Log is
displayed on the screen, allowing the user to send the text
directly to a printer rather than having to go through an
auxiliary text editor.
libraries modified – An inconsistency arising when
using a Windows 98 based operating system with a new release
of our third party spreadsheet library in which some characters
were dropped from the spreadsheet display, has been resolved.
of Flexible Joints Changed – Flexible joints are now
represented differently (extruded 4-point star) on the piping
system rendered graphic display than are rigid joints (extruded
square). This change is in preparation of including the
actual shape and orientation specification for flexible
members to be displayed in a later release.
of Dampers Changed – When dampers are specified they
are now displayed in the graphical representation of the
piping system as shown in both line and rendered mode.
Spreadsheet for Anchor Forces and Moments – The copy
spreadsheet function left off the last line when trying
to transfer information from TRIFLEX® Windows to Excel
or a similar spreadsheet. This problem has been corrected.
Wind Load at First Anchor – TRIFLEX® Windows now
allows setting wind load at the first anchor such that it
can be rippled to succeeding components. Previously this
action caused a program malfunction.
of Input Spreadsheet – TRIFLEX® Windows no longer
experiences difficulty when trying to print the input spreadsheet
prior to running a calculation.
Database Changes Accessible – The valve component
dialog now works properly and recognizes user changes made
to the valve database.
modification to 12” Pipe – Previously the database
entry listed an incorrect value for the default wall thickness
for 12” Schedule 80 pipe. This is now corrected to
the ANSI standard value.
Default Reducer Length Modified – The default reducer
length used by the reducer component dialog has been changed
such that the same length is given regardless of whether
the reducer is used as an expander or reducer, hence direction
of coding the system no longer is an issue with regard to
default reducer length.
API 610 Input Dialog – The API 610 input dialog now
functions properly, recognizing the update command button.
Graphic Print of Empty System – If no components have
been defined, selection of the FILE/ PRINT menu item no
longer causes a program crash.
