TRIFLEX® Version 3.3.1 Enhancements & Modifications

April 5, 2010

Enhancements

1. Output Results and Code Compliance Column Headings - This version of TRIFLEX adds the ability for users to customize the column headings they see within the program and when exported to EXCEL. If foreign ASCII fonts are available, using Windows settings, these headings may be set to their foreign language equivalents. A file COL_head.txt is included in the TRIFLEX installation folder, which may be edited using the included instructions, to produce these custom headings. Should the file be modified, the user should save the file to a location other than the TRIFLEX installation folder so that it may be recalled when later versions of TRIFLEX are installed.

2. Installation Folder - The default installation folder for TRIFLEX will no longer be C:\Program Files\PipingSolutions\TRIFLEXWindows, as it has been in the past, but C:\TRIFLEXWindowsX.X.X where X.X.X is the version of TRIFLEX being installed. This change will ease the user's discomfort when dealing with the Vista and Windows7 User Access Control (UAC) which in Vista, at least, by default prevented writing to the Program Files folder where a large number of TRIFLEX intermediate files are located.

3. PRV Flanges - The Pressure Relief Valve component dialog, correcting a previous oversight, now contains provisions for specifying a flange on the outlet side different than that on the inlet side, since typically the diameter at the outlet is larger.

4. Additional Case Defaults - When additional load cases were added to the piping model the default allowable stress for various piping codes was the allowable stress set in the first case defined. This has been amended such that now the correct allowable stress for the operating temperature specified for that case will be used as the default.

5. EXCEL Export - The EXCEL export function no longer uses the C:\ root directory as a temporary file location, since this directory is set to read only in many Windows installations.

6. Material Databases - The material databases for ASME B31.1 and ASME B31.3 have been updated to the latest releases of the code, 2007 for 31.1 and 2008 for 31.3. The Euro Code data base has been amended to reflect data contained in the 2002 10216-1 through 10216-5 documents.

7. Operating Temperature in Euro Code - A has been added to the Euro Code dialog which gives the operating temperature, along with the allowable stress and creep stress range, on a case by case basis.

8. Case Definition Dialog - The functionality of the case definition dialog has been improved such that when either time history or response spectrum as occasional loading boxes are checked, the perform piping code analysis box is also checked. This box has always needed setting, but previously it could become overlooked and the proper analysis would not be carried out.

Modifications

1. EXCEL Export - The EXCEL export function in TRIFLEX no longer uses the C:\ root directory as a temporary file location, since this directory is set to read only in many Windows installations.

2. Character Set Saved - The character set along with the other parameters defining the report font for use in the special reports, output and Piping Code reports and export to EXCEL is now being saved.

3. Euro Code - Several modifications and corrections have been made to the Euro Code to insure its accuracy and usefulness.

4. Print Preview and Print Report - The previous version of TRIFLEX, the Print Preview and Print Report items were removed from the Output Menu list, however, the icons were left on the Main Toolbar and the faulty routines could still be accessed. As mentioned in the previous Enhancements and Modifications document, this causes memory overwrites that can lead to random program crashes. The icons have now been removed also.

5. Material Selection Dialogs - No longer will one be able to select a material other than a generic material or from the database pertaining to the piping code selected in the modeling defaults setup. This applies to the Pipe Properties tab on the component dialog as well as the Anchor Movements tab on the anchor dialog.

6. PCF Export and Import - PCF export and import functionality has greatly improved with provisions added such that TRIFLEX will accept some non-standard formatted files and will recognize a larger variety of optional constructs. Also the export functions corrected problems occurring with reducers.

7. Operating Temperature Ripple - A bug in the previous version when operating temperature was rippled would ignore the fact that the Ripple This Case box was unchecked and ripple the temperatures for all cases regardless of the setting. This has been corrected such that individual cases can be set to be exempt from the ripple operation if desired.

8. Occasional Loads with Load Case Combination - When occasional loads are not specifically defined on a combined case, no longer will the columns in the code compliance report be displayed which relate to occasional loading.

9. Output Report List - The output report dropdown no longer lists the modal participation report unless the case being viewed is specifically defined to be a response spectrum case.

10. Structural Members - Specifying 1 inch round bar previously would cause a problem because the initial '1' in the specifying text string would match the initial '1' in the specification for '1/16" round bar' Compounding the problem, the moment of inertia for 1/16 rod was so small that it could not be accommodated by TRIFLEX. Making the match extend to all characters of the specifying string and eliminating rod smaller than ╝ inch in diameter rectified both issues.

11. Zero Period Acceleration - Specifying ZPA in a response spectrum analysis has become less problematic, with better error messaging detailing the required procedure and detecting error conditions before they result in bad program behavior.
