Version 3.0.0 Enhancements & Modifications
1. Expanded Data Point Output – TRIFLEX® output
reports are configured to give calculated data at those
locations necessary to evaluate the system response. A new
option has been added in the Model Defaults Dialog, which
expands the output so that data is given in the reports
for each Run Begin as well as each Run End. This will alleviate
some problems previously faced when a restraint in the absence
of other system geometry changes resulted in a discontinuity
in shear stress, which was not reported. Care should be
exercised when using this option, however, since it may
lead to extremely long reports containing quite a bit of
Load Case Combination – The capability has been added
such that load cases defined and calculated may be combined,
using a variety of methods, into a new case. This new combined
case has all the properties of a case defined from the outset,
before the calculation. It may be viewed using the View
Analysis spreadsheet, the Code Compliance spreadsheet, or
any applicable Special Reports. Further, once defined, a
case can be used in the definition of other combined cases.
to Previous Version – Previously data files created
and saved in given version of TRIFLEX® were not available
to be opened and examined in an earlier version. Starting
with this version of the program, files can now be saved
which will be compatible with earlier versions. When such
a file is saved, however, it may loose data which is not
recognized by the earlier version, and when reloaded into
the current version that lost data will be replaced by whatever
defaults may apply. Also, the version of the program with
which the file was saved may now be seen using the “Main
Menu/Utilities/Data File” command.
Selection – Output report spreadsheets may now be
viewed and printed with a font face and size selected by
the user. In order to change the font, use the “Main
Menu / Setup / Set Report Font” menu item. All row
and column sizes have been adjusted such that all data is
included on the initial report, regardless of the font used.
French Code S.N.C.T. Tuyauteries – The French Codeti
code has been added to the TRIFLEX® output piping code
Analysis Results – The View Analysis Results report
options have been expanded to include a report including
a report for all load case combination definitions. Further,
the printing of this spreadsheet includes the option to
print the currently displayed report. This is essential
if it is desired to obtain hardcopy of a spreadsheet in
‘Case Order’ since the normal results display
the results for a single selected load case.
Import – The spreadsheet import capability of TRIFLEX
has been expanded to include the entire selection of components,
allowing the basis of system geometry to be input into TRIFLEX®
in this manner.
Property Evaluation – A slight modification has been
made to the property evaluation routines for B31.1 and B31.3
materials when the temperature specified is exactly equal
to the temperature limits of the material. A formal interpolation
is now done if the temperature is exactly equal to the limit,
rather than defaulting to the lower or upper end of the
property table as was done previously in this instance.
No cha nge will be evident should the temperature be set
to any value other than the exact upper or lower limit.
Material Database – The entries for the expansion
coefficient for Austenitic Stainless Steels at 200 and 1200
degrees F were found to be in error and corrected to 1.46
in/100ft and 14.20 in/100ft respectively.
Participation Factors – No longer does the drop down
report selection in View Results erroneously list Modal
Participation Factors when spectral information is not available.
Previously this could happen if some case definitions were
Calculations – Error checking and correction has been
implemented in various dialogs which utilized angle calculation
routines. These include the Expansion Joint dialog, Release
Element dialog, Anchor dialog, and Wind Load dialog among
others. Occasionally certain combinations of data could
result in numerical rounding which would invalidate further
mathematical manipulation with that result, leading to a
Graphics – The rendered image of fixed anchors has
been modified for smaller diameter piping such that the
size of the anchor element corresponds more closely with
the attached pipe diameter. Previously the minimum size
drawn was approximately 3.5 inches square which proved to
be too large to adequately represent piping with diameters
less than 1 inch. This is a graphic change only and does
not affect any calculation.
Calculator – The inability of the LNG calculator to
properly pass a custom direction vector back to the input
dialogs of the anchor and release element has been corrected.
Analysis Results Sorting – When the View Analysis
Results spreadsheet was listed in Case Order, as opposed
to Data Point Order, if case names were large, errors could
occur when using the sort function (double-click on the
column). This problem has been resolved.
Table A2 Materials – Previously when a material was
selected from the B31.1 Table A2 for Low and Intermediate
Alloy Steel, the allowable stress as evaluated by the program
could be in error, depending on the operating temperature.
This release corrects that deficiency.
B31.5, and SPC2 Codes – Three piping codes were found
to have problems in serialization, preventing data files,
once saved using the piping code, to be properly read back
into the program. The problem originally appeared at the
transition to unlimited load cases in version 2.6.0 and
has now been corrected.
Fitting Thickness – Elbow or bend fitting thickness
was not converted properly if ANSI pipe sizes (diameters
in inches) were used in SI, MKS, or IU1 unit systems and
a thickness other than the default was specified. This problem
has been corrected.
Output Spreadsheet Reports – An error which occurred
following the export of the output data to an EXCEL spreadsheet
or to an iOut file for use in creating Stress Isometric
drawings, wherein the unit field in the spreadsheets were
truncated to two characters, has been corrected.
Flange, Valve, and Pressure Relief Valve – Data base
components now require a non-zero delta dimension entry
before the data entry dialog may be finalized. This prevents
a problem which occurred when a component could not be found
in the data base, was initiated with zero total length,
and, if left with no length entry, disappeared from the
graphical representation of the piping system.
ST-SL Generic Type 310 Stainless – The material database
failed to differentiate between ST and SL generic stainless
steel entries. The ST entry has been modified such that
it is now clearly labeled PRE 1990, as it should have been.
PCF Import – The PCF import routine has been modified
such that if a coupling component is connected between the
end nodes of a piping element, an additional node will be
generated to support the coupling.
