Removing supports for ASME B31.3 2014 or later models using support liftoff can cause an application crash when running the analysis output subreport. This is due to a memory request for the names of points containing supports that were removed during analysis from liftoff.
As this is file specific, if a crash occurs in a particular model, avoid printing the analysis summary subreport. If this is the issue causing the crash, a crash should not occur.

Steps to reproduce:
1. Open Walkthru model2. Change piping code to B31.1 (2012 edition)3. Open the pipe properties dialog for the pipe ID available and set "Long weld E fact” as 0.88 and “Long weld WL fac” as 0.924. Press F3 on any point
Observe that the Point Properties window only show ZL and ZC weld factors but not the "Long weld E fact” and “Long weld WL fac” weld factors.
5. Take out the Pipe data listing report
Observe that the values for E and W are both displayed as 1.0
Note that the header labels for B31.1 (2014) edition for pipe data listing would also need to be updated. The display of weld factors on the F3 window would also need to be done for B31.3 (2004 and later editions) also.

The intermediate soil points are inheriting the SIF properties from the –ve and +ve faces of the previous bend node. The -ve faces of the intermediate nodes inherit the -ve face of the previous node, and the +ve face of the intermediate nodes inherit the +ve face of the previous node.
SIF values on soil points directly after bends will always be higher than they should be, causing conservative results. It is suggested that these results be ignored. An approach that is not recommended, but will resolve the SIF error, is to place a run point very close (~0.01 inches) to the far node of a buried bend, and set that element to be soil free. It shall resolve the SIF error, but the lack of soil springs on that element may affect the displacements on the model.
SAM results for supports skewed off of the global axis may not be consistent with supports on the global axis, although the local axes relative to pipes are the same.
Align all piping nodes containing supports to the global axis using Edit > Rotate, then run SAM analysis.

When modeling : Anchor-Pipe-Anchor-Pipe-Anchor.Running a static seismic cancels the moments on the mid-anchor because of its symmetry. A designer who is not attentive may only use the M = 0 from the "Restraint Reaction" page, and not think of checking the moment from the "Global" page. It is more difficult to catch of course if the model is not symmetrical, and prints the difference of element moments from each side instead of the sum.
Suggest reporting the Max (+ & -) of the Global forces and moments about anchor points

Inconsistent allowable values may be reported for a tee that has different pipe materials across different legs. This applies to ASME NB and JSME Class2 Piping codes, where tee moment summation is applied for calculating stress values for the tee component. Based on the arrangement of the pipe materials for different tee legs, the allowable stress value for certain tee legs may be reported higher than the actual allowable value for that leg’s material which may lead to un-conservative results.
To illustrate the defect the following scenario can be considered:
Step 1: Create a new class 1 model with Edition set as 2007Step 2: Create a pipe ID M_HIGH, with 12” nominal diameter and material selected as SA106CStep 3: When prompted for Design Pres & Temp, enter Design Temperature as 200 deg FStep 4: Insert an anchor in the model at A00 and invoke Tee Point dialog (Insert > Tee)Step 5: On the Tee Point dialog, enter 10 feet in DX direction, select “Pipe data identifier” as M_HIGH, “Tee component” as Tee, “From point orientation” as 1-Header and Type of tee as Welding and press OKStep 6: Click on the small blue arrow at point A01 pointing in the same direction as the header and invoke “Insert > Run”Step 7: On the Run Point dialog, enter length as +10 in the DX direction with Pipe data identifier selected as M_HIGH and press OKStep 8: Now select the last remaining arrow pointing perpendicular to the Tee header and invoke “Insert > Run”Step 9: On the Run Point dialog, enter length as 10 feet, enter 10 feet in the DZ direction and overwrite Pipe data identifier with M_LOW and press OKStep 10: On the Pipe Properties dialog that appears, enter 12” nominal diameter and select material as SA106A Step 11: Analyze the model and take out Preliminary Stress report for the model
A value of 34,950 psi (1.5*Sm = 1.5*23,300) is reported as Equation 9 Allowable for both the header and branch of tee point A01. Notice that the lower value of Design Sm of 16,000 (resulting in 1.5*Sm = 24,000) for Pipe ID M_LOW having pipe material SA106A is not taken into consideration when calculating the allowable value.
For JSME PPC piping code, this issue is only observed when the tee header is constructed of two different materials having different hot allowable Sh values i.e. two different materials used along the two legs of the header pipe.
The following considerations are provided to assist in your evaluation of the potential impact of this defect on the results:
1. Evaluate whether this defect has affected any existing models by considering the criteria below:a. Was the model created in program version 9.1.0 or later? b. Was the piping code for the model set to any one of the following two piping codes?i. ASME NB Nuclear “1974 + 1975 W addenda” edition or laterii. JSME S NC1 Class 2-PPC 2005 edition or laterc. Was there a tee in the model having different material used along different tee legs?
A 'No' to one or more of the above criteria means that this defect does not affect the model’s results. No further consideration for this model is necessary.
2. Otherwise, the following mitigating conditions should be considered:a. For JSME piping code, this defect is only observed is there is a change in material along the tee header. Having different material for Tee Header and Branch of the tee component reports correct allowable values.b. For JSME piping code, this issue is not observed if the “Apply tee summation” result model option is uncheckedc. For ASME NB piping code, if there is no change in material along the tee header then the allowable values are always calculated based on the tee header material
Important Note:ASME NB code does not clearly define whether the allowable value for a tee component shall be calculated using the minimum Stress intensity and yield strength from Header and Branch of a tee. However, response from ASME to an interpretation request from AutoPIPE team tends to suggest that the conservative approach of taking the minimum stress intensity / yield strength from the Tee header and branch is allowed / favored by the committee. Please see the response from the ASME committee to the question below:
Question: If a branch connection is constructed of different material specification for Run and Branch does the code prohibit using the most limiting allowable stress intensity value for equation 9 and equation 10?Answer: No
Manually enter the most conservative Hot Allowable value for affected tee component legs under Pres/Temp/PipeID tab of Review Component Data grid.
After creating an output report the active window should become the Report Viewer instead of the program window.
1. With any model opened, create an output report
2. After the Report Viewer is automatically display, use the mouse wheel or press the keyboard PgDN Key / Cntl+ Print. The program Window reacts, sending the Report Viewer Window to the background behind the program window. Request that the Report Viewer window become the active window when opened

Description: Add feature to display total pipe length for each PIPE ID and grand total pipe length data at the end of the Extended Data Listing report
Workaround: Insert Fluid transient flow path along pipe length to be measured, one the THL file is created review report looking for "TOTAL WAVE TRAVEL LENGTH (L)". Perform as needed for each measured length required.
AutoPIPE currently provides the Weight of Empty Pipes, Weight of Contents, and Total Weight of System per model in the model listing output report. An enhancement request has been made to provide the same information per user selection of piping in the current model.Client suggested it would be useful to have this feature as a measuring tool (similar to the distance command).
Add option to view beam displacements in results grids. This could be very useful when working with civil structure departments in reporting thermal displacements. Reporting pipe displacements is excessive and leads to overdesigning of support structures and foundations.
