Can OBS accurately model for HDPE Pipe?

Except for the Level 3, the software can be used for stability assessment of HDPE pipes.

The level 3 uses a beam-element type of finite element approach that takes the stiffness of the pipe into account. However, the software has only been applied to steel pipes and no validation has been conducted on using Level 3 for analysis of flexible pipes.

Therefore, it is not recommended to use Level 3 at this stage.
