Hi all
I have been trying to model above ground pipeline which the pipeline is laid directly on the ground.

I set up user defind soil model (all zero except dwnword load and stiffness) and soil cover set to zero.

I try to run soil model but execution is stoped with
"Kup or Kdown, and either Pup or Pdown must be specified. Check all stiffness values for nonzero entries".
I cannot go any further. Well, Kdown and Pdown have been entered. What is wrong? I am missing something?

Regards,

Nojima

The CAESAR II Buried Pipe Modeler assumes the pipe is buried. The modeler won't work properly if you specify the "buried depth" as zero.
