Problem:
Why does program crash when executing Strength calculations of a tall column with several trays?
Is this because there is a limit on the height of the vessel?
Why does it happen and how to correct this?
Solution:
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:
FIGURE 1
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:
FIGURE 2
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.
Please note - reduction of the conical skirt in these scenarios may also resolve the problem and the reason for that is a conical section creates several different sections in the beam model (and consequently several points of load), so when the user decreases the length of the skirt then the number of loads is decreased.
