Multiple Load Cases – This version of TRIFLEX®Windows includes the option to
select and calculate a number of load cases limited only by the capabilities of the computer,
in essence, as many as the user desires. A great many dialogs have been modified to be able to
accommodate a variable number of cases, including the Case Definition dialog, the component process
page, the Anchor movement page, those code compliance pages where provision is made for multiple
allowable stresses, the fatigue cyclic loading dialog, etc. Each defined case must be assigned a name
(default if the user desires). Ways in which dynamic calculations were handled previously with fixed
case numbers is now revised. The case selection dropdown on the main menu lists case index, case name,
and case description.
Direct Stress Isometric Drawings – TRIFLEX®Windows now produces Stress Isometric Drawings
in DXF format, including User selected stress tables, which contain information calculated by the program
and available in the View Analysis Results reports. This may be displayed using AutoDesk's AutoCad, using
the export to DXF menu item. As with various other optional features, this capability is initiated and
controlled by the security activator of TRIFLEX®Windows.
Export to Excel – TRIFLEX®Windows now exports all reports to Microsoft Excel
spreadsheet with each report on a separate worksheet.
Euro Code – The European Code Compliance Dialog has been modified such that Creep Stress
range calculations may be turned on or off at the User's discretion.
Ignore Temperature Limits – Another option has been added to the Code Definition Dialog
under the Setup menu tab, such that the user may completely ignore any temperature limitations on the material.
This is in addition to the check box that already existed such that the user could simply relax the material
temperature limits to those within the range of available properties. Property data and allowable stresses are
taken as the values at the lowest or highest temperature available for the particular material depending on
whether the actual supplied temperature is lower or higher than that strictly allowed by code. These data
may then be modified by the User if desired.
Merging of Pipe Components – When a continuous run consisting of non-branching pipe
components is selected, the User may merge this into a single pipe component by using the new
Main Menu/Edit/Merge command. The single pipe that replaces the run will have the properties associated with
the first selected pipe, in component list order.
Response Spectrum Definition Page – The response spectrum definition page has been
redesigned both in appearance and function, such that the operation is more intuitive and easier to follow.
As one example, if a spectrum is input manually using the spreadsheet, the User is asked if he/she wishes to
save the spectrum, either to file or memory, before exiting the dialog with it unsaved.
View Analysis Results - Piping System Movements – Two new columns have been added to the
Piping System Movements report, giving the resultant deflections and resultant rotations in addition to movements
along and rotations about the global axes.
View Analysis Results to Component Dialog – Where applicable, double clicking on a row in a report
in any View Analysis Results spread sheet, will bring up the dialog for the component referenced on that row.
Further an extra column, "Data Sequence", has been added to some reports in the View Analysis Results, such that
sorting on that column will restore data to its original order, if it has been reordered due to a sort
on another column.
Anchor-Anchor, Anchor-Restraint Warning – Occasionally in coding a piping system, an anchor
can be placed at the same node location as another anchor or a component with a specified restraint.
While this will not necessarily invalidate the calculation, the results may not be that which were expected.
A warning message is now issued before the calculation should such a configuration be encountered
in preliminary checks.
Branch Selection – When selecting a branch of the piping system using Shift - Left Click
on the mouse, if the User was pointing to a restraint symbol rather than an actual component rendering
at the time of the Shift - Left Click action, an error would occur. This problem has been resolved such
that pointing to a restraint is now handled the same as pointing to the component on which that restraint
Selected Bend or Elbow – A bend or elbow drawn in line mode now has a line width consistent
with other components whether or not it is selected. Previously, the width of line used to draw elbows or
bends was not affected by the state of selection.
File Name Length Warning – Occasionally, when using long file names in deep folder structures,
it became possible to exceed the path name restriction of 256 characters imposed by Microsoft Windows when the
program was trying to create and store intermediate files. This would cause an unexpected crash during the
calculation phase. A warning message is now issued during loading and saving of data files should the user's
choice of path name become long enough such that problems would later be encountered.
Valve Operator Weight Reset – Previously, when multiple valves existed within a piping system
and an operator weight was specified for one valve, that operator weight was automatically assumed for all valves
that followed in the Component List. This feature has been revised such that operator weight is no longer rippled
automatically. If the user wishes operator weight to be considered on a valve, he/she must explicitly enter the
operator weight in the Valve Entry Dialog.
European Comma Decimal Separator – When Microsoft language settings were used specifying the comma
character, rather than the period, as the decimal separator, some spreadsheet information would be lost.
This problem has been resolved.
Annotation Overflow – Node numbers and component names displayed on the graphic display could,
under certain circumstances, overflow onto the bottom corner of the display screen when zoomed or panned off the
screen instead of simply being clipped. The problem has been corrected such that this text is clipped when it
leaves the viewable area..
Code Compliance Report Value Rounding – In previous versions of TRIFLEX®, some values, in particular
integral percentage values, in the code compliance reports were reported by truncating the fractional part of the
number beyond the number of digits given. All values in the report are now properly rounded.
Restraint Selection Display – When selecting a component, through menu or mouse, any attached
restraint no longer shows the highlight or selected color indication. This removes the problem wherein the restraint
and associated component lost synchronization, during saves and recalls or when showing selected components, indicating
that the restraint was selected but the component not, or vice versa. Ctrl-Left click on the restraint still selects the
associated component as it always did, however. The only change is that the restraint itself is not drawn as selected.
Skewed Restraints – An error in calculating the system behavior due to skewed restraints specified
with a direction vector was corrected. This no longer results in a single X direction force or about X rotation, but
behaves as expected.
API 610 Dialog – The dialog for API 610 centrifugal pump entry had been updated and the logic
has been rewritten to more accurately display the requirements for analysis using the 6th and 7th
edition of the code.
View Analysis Results Local Forces and Moments –The local forces and moments report has been modified
to bring it into compliance with the local movements report. Note that local axes for components are defined as L, N,
and G with the L, or longitudinal, axis corresponding to the axial direction, the N, or normal, axis corresponding to
that direction perpendicular to the L axis with the minimum divergence from the global Y axis, and the G, or guide,
axis the cross product of vectors in the L and N directions. Further restraint forces and moments are shown in this
report as seen from the local axis perspective.
