TRIFLEX® Windows 2.5.4
March 7, 2005

Enhancements

1. Anaglyphic View – An option has been added to allow the User to view the piping system in anaglyphic 3D mode using glasses with red and cyan lenses.

2. Coade Neutral File Import – Neutral files produced by Coade's CaesarII version 4.5 may be imported into TRIFLEX®Windows which allow Users to convert data originally coded in CaesarII such that it can be processed with the superior analysis tools offered by TRIFLEXâWindows.

3. Modal Participation Factors – The modal participation factors output spreadsheet has been enhanced to include a summation of the modal participation factors multiplied by the mass of the system. This gives the User an indication of the overall effectiveness of Response Spectrum dynamic modeling based on the number of vibratory modes chosen to approximate the system reaction. As this participation factor summation approaches 100%, the analysis more nearly predicts the actual behavior of the piping system.

4. .NET Technology Incorporated – This release of TRIFLEX®Windows marks the adoption of the Microsoft .Net Technology. Changes will be evident in the installation of the product, as well as, for Users of Windows XP operating systems, the appearance and style of the program dialogs and controls.


Modifications

1. B31.3 Carbon Steel – The minimum temperature calculation on B31.3 Carbon Steel materials that are not given by a material thickness dependent lookup table in the code, but only by a fixed temperature, have been modified to correctly recognize and convert this fixed temperature.

2. Expansion Joint Data Dialog – The unit designation for the minimum length field was corrected to reflect the correct unit system chosen for data entry.

3. Export to HTML – When the piping code report spreadsheet was being exported to an html file, occasionally the numeric data would be displayed such that only those numbers in a particular column with the largest number of actual characters could be seen. This problem has been corrected by our third-party spreadsheet library supplier, and the revised DLLS are included in this release.

4. Showing the Pipe Node Coordinate hidden in Elbow Drawing – The graphical representation of the piping system now shows the node designation when a minimum pipe length is specified after an elbow. Originally this node display was shown at the joint point and was visible only in Line/Render mode.

5. Blank and Empty Dialog Fields – Several fields in the component data entry dialogs (particularly those pertaining to SIF factors) were programmed such that if no data was to be entered and the field was to assume the default value, they were required to be empty; that is, no characters at all. This requirement has been relaxed such that whether the field is empty, populated with blanks or other white space characters, it is treated as empty. In particular, the Branch, Elbow, Flange, Pipe, Reducer, Valve, and the Expansion Joint component dialogs are affected by this modification.

6. Pressure, Shape Factor Entry of Wind Load – When entering wind loading using the Pressure Force - Shape Factor entry method, the loading was miscalculated by a factor dependent on the input unit system due to unit conversion. This problem has been corrected.

7. PCF File Conversion – The PCF file format contains the facility in the file header for the specification of the unit system to be used in interpreting data for the remainder of the file. When the TRIFLEX®Windows import routine did not find such a specification, it failed to import the file. The requirements are now relaxed somewhat such that if a reasonable assumption can be made for the weight unit, for example, based on what is supplied for the length unit, then the import will proceed.

8. Water Hammer
– The worksheet for calculating time and force loading for a water hammer event in the Time History analysis has been corrected such that Bulk Modulus is correctly supplied for fluids in unit systems other than English Units. Also, the time and force calculations have been corrected to accurately account for differing unit systems.

9. Rippling Process Temperature – When rippling process temperature using unit systems other than English Units, occasionally the allowable stress as shown on the code compliance dialog would be modified to the numerical equivalent of the English Unit value of the allowable stress at that temperature, rather than the value associated with the unit system chosen. This problem has been corrected.

10. Euro Code Wall Thickness – The Euro Code calculation of required wall thickness has been modified to correctly account for variable operating condition allowable stresses, as well as a User-defined joint coefficient.

11. Transparent Mode Compatibility – No longer does visualizing a component in transparent mode set up a flag that interferes with other drawing mode flags such as the Line Draw/Render flag, thereby correcting a problem that existed with components being stuck in a particular drawing mode as the modes were changed.

12. Sea Level Settings – The setting for sea level in the Model Definitions Dialog is now retained along with the other design parameters on the dialog when a piping system is saved. Previously this field was lost when the model was saved and then recalled.

13. Reducer Dialog Update – The reducer length field in the reducer input dialog now updates properly when the inlet or outlet segment diameter (which ever is greater) is changed.

14. B31.3 and B31.1 Materials Selection – The selection dropdown lists for B31.1 and B31.3 materials have been modified such that only unique selections are displayed and such that the specification and material choices are arranged alphabetically and, hence, easier to locate.
