Windows Version 2.3.1 Enhancements & Modifications
September 30, 2003
Node Location – Previous versions of TRIFLEXâWindows
used an algorithm for node location that could drastically
alter the users point of view of the piping system since
it rotated the camera to point at the node in question.
A revised algorithm has been implemented in this release
that will pan the camera to a point adjacent to the node
to be found, leaving the camera rotation fixed.
2. Loading System Data File with PRV – When attempting
to recall a piping system saved with a pressure relief valve,
the program would exit abnormally. This error has been corrected.
Database Format – In order to accommodate our Win9x
customers without Microsoft Office 2000 or greater loaded,
the TRIFLEXâWindows database previously defaulted
to Access 97 format. While there were means available such
that the Access2000 format database files could be utilized
from within the program, it was not an easy task to do so.
Starting with release 2.3.1, TRIFLEXâWindows will
check to see if Access2000 format files can be used on the
computer, and, if so, present the user with a choice of
Access2000 or Access97 formats.
of B31.1 Materials – When a material is chosen from
the B31.1 compatible database, the density of that material
is now selected properly and displayed in the Pipe Properties
tab of the Component Dialog.
Ripple – Rippling Material from the Pipe Properties
tab or Temperature from the Process tab of the Component
Dialog, with a B31.1 material selected, now properly sets
or adjusts the physical properties on the Process tab, and
the stress allowables on the Code Compliance tab for all
Import of Structural Members – The keyword file used
to transfer system data to the calculator, has no means
of storing the type and designation of structural members
as a part of a flexible joint, and therefore, when such
components were imported into TRIFLEXâWindows from
a keyword file, these fields were left blank. Previously
the Joint Component Dialog would not allow the user to exit
the dialog without having these fields populated. To populate
them with other than the correct information would overwrite
the cross sectional area properties, which were imported
correctly. The requirement for having these fields populated
is relaxed as long as there is property information available
on the dialog.
Intensification Factors for Reducers – The default
stress intensification factor for reducers is properly applied
to the reducer and its connecting pipe ends as a function
of the particular piping code selected by the user at the
time the reducer dialog is called up and the reducer is
added to the piping system. As always, the user is free
to override the default values at his discretion.
Stops and Friction – An error appeared in version
2.3.0 of TRIFLEXâWindows wherein limit stops and friction
restraints could not be applied to the same component. This
problem has been rectified.
Materials Display – With the advent of long names
used for the materials derived from the B31.1 compatible
database in version 2.3.0, several issues arose regarding
the display. Among these are the material name shown on
the output spreadsheet, on the input parameter scale when
showing system materials, and on the Process tab of the
component dialog where the name was truncated inappropriately.
These issues have been identified and corrected.
Reducer Dialog Title Block – The title block on the
reducer component dialog mistakenly identified the component
as a ‘flange’ rather than as a ‘reducer’.
This has been satisfactorily resolved.
Renumber and Special Reports – The renumber function
as implemented from the Edit Menu or using the Ctrl+R hotkey
now goes into data entered for API610, API617, Flange Loading,
Rotating Equipment, and NEMA reports and modifies the node
numbers for this data to correspond to the new node designations.
If data has been entered through these dialogs and the user
wishes to renumber the system, no longer is a manual edit
