1. Interchange Axes – A new feature
has been incorporated where the user can interchange coordinate
axes for a selected set of components. This allows, among
other things, the rotation of the selected components by
90 degrees. Also the dialog for axes interchange includes
the ability to ‘Flip’ axes without having to
go through the copy-paste routine allowing ‘mirroring’
of the selected components.
2. Mouse Scroll Wheel – TRIFLEX®Windows
now allows the mouse scroll wheel to be used to zoom in
and out of the graphic model. The use of the wheel is analogous
to the software thumb wheel on the right hand side of the
3. View Results Spreadsheet Reports –
Several additions have been added to the View Results spreadsheet,
including viewing reports for selected components only and
viewing selected reports sorted by load case rather than
by data point. Those reports that may be viewed by load
case include Anchor Movements and Forces, Restraint Movements
and Forces, and Global Movements and Forces. These reports
may include or exclude sub cases, and, should a dynamics
time history case be available, they can give a detailed
listing of all available items versus time.
1. Input Spreadsheet Temperature and Pressure
– Adding or deleting cases did not increase the number
of columns shown on the input spreadsheet and therefore
the spreadsheet could not display the temperature and pressure
associated with the extra cases. This problem has been corrected
by updating the spreadsheet if necessary after leaving the
Case Definition dialog.
2. Thermal Expansion Coefficient for FRP
– The thermal expansion coefficient for FRP/GRP piping
in the database now properly updates with base or operating
condition temperature changes.
3. Number of Loading Cycles – In
the changes made to the previous version, the transfer from
dialog to system data storage for the number of loading
cycles used in calculating fatigue usage factor was inadvertently
short circuited. The connection has been reestablished.
4. Fatigue Analysis – The previous
version curtailed fatigue analysis only to the first six
load cases. This restriction has been removed and all defined
cases now participate in the analysis and computation of
cumulative usage factor.
5. Process Data in Code Compliance Dialog
– The communication between the Process tab and the
Code Compliance tab in the component entry dialogs have
been corrected such that temperature data entered for an
operating condition of a particular case is properly reflected
in the allowable stress for that case. This was an issue
in B31.1 and B31.3 Code compliance analyses where allowable
stress is retrieved from material tables. In the remaining
codes, or for generic materials, the value of allowable
stress is to be entered by the user.
6. Allowable Stress Entry – The
previous version of the program (2.6.1) had a malfunction
which prevented allowable stress modification by the User
in a number of code compliance dialogs, including the Norwegian
(TBK51 and TBK52), Swedish (SPC1 and SPC2), Navy, Nuclear
Codes (ACL2 and ACL3), Euro Code, and B31.5. In these codes
the default value of allowable stress for a particular material
was selected. This problem has been fixed and users are
able to modify the allowable should they wish to choose
a value different from the default.
7. Piping System Properties Report –
The temperature column of the Piping System Properties Report
in the View Analysis Results Section was not reported properly
for a case index exceeding six. This was a carry over from
the previous limitation of six load cases that was removed
in the last release. This problem has been corrected.
8. PCF Import – PCF import capability
has been improved to include o-let and tee-set-on which
connect to the centerline between the end points of a pipe.
These elements previously were flagged as erroneous due
to the TRIFLEX?Windows rule stating that all piping system
connections be at defined nodes. Further, all components
not recognized by the import engine are treated as rigid
joints, thus solving related connectivity errors. Should
there be problems with importing, the User should verify
the connectivity points on the PCF file itself.
9. Dynamic Analyses with Fatigue –
Another problem associated with the expansion of possible
load cases from six to any number required, was an error
in the reporting of Code Compliance data when a fatigue
analysis was requested along with a dynamic analysis, either
Time History or Response Spectrum. This release rectifies
10. Copy and Paste with Unlimited Load Cases
– A problem was found when trying to copy portions
of piping systems to other systems when the two had a different
number of defined load cases. In versions prior to 2.6.1,
a predefined number of six cases was assigned to all piping
systems so this was not a problem; however, now, the case
number is variable. Program modifications have been instituted
which will make the pasted to system the controlling parameter,
so the number of cases for those components on the clipboard
will be adjusted to be equal to that of the system to which
they are to be pasted. Process and code compliance data
is carried over from the clipboard to the extent to which
it is applicable.
11. Modal Participation Factor Report –
An error preventing the Modal Participation Factor report
from displaying has been fixed.
