Problem:
"Bentley AutoPIPE Vessel Design and Calculations has stopped working" message appears when running Strength Calculations on a tall vessel
Why and how to avoid it?
Solution:
Reason A:
There is no restriction on the height of column in AutoPIPE Vessel, however the crash may occur because excessive number of loads being applied due to very large number of trays and or attachments as shown below:
Reason B:
AutoPIPE Vessel has a limit of upto a maximum of 400 loads that can be applied for the beam model. A workaround could be to replace some trays and accessories and replace them by a single equivalent internal (vertical load) as shown, that way it would reduce the total number of applied loads and keep it within the limit specified above:
The top 2 sets of trays (total 35) in figure 1 is replaced by an equivalent vertical load of 103005 daN as in Figure 2.
The file executes without a problem when the weights of the trays are replaced by the equivalent load as shown above
Reason C:
The crash may be due to an inconsistent value of wall thickness settings (ex. 16.65 mm) minus corrosion thickness (ex. 28 mm).
The difference between wall thickness and corrosion was found to be a negative number or zero (example: 16.65 – 28 ==> 0 mm), This leads a division by zero and the program crashes. A new enhancement thas been logged to provide a sanity check for wall thickness to prevent this from happening in the future.
