Hi,
I am trying to model a pipeline buried in sand. Elastic properties of the sand is assumed.
I was able to do this succesfully using shell-solid as shown in the attached file "Buried pipe (solid-shell).mph". This is exactly what I want to model and the results are good. However, I want the pipeline to behave like an Euler-Bernoulli beam.
I have tried to make a buried beam in the file "Buried pipe (solid-beam).mph" but the simulation fails. I think the connection between the beam and the soil is not properly defined. I want continous contact between the beam and the solid.
On a side note, I would like to make the connection between the solid and the shell smooth in the first model. Is this possible? I see no such option in the Solid-Shell Connection tab.
Best regards,
Daniel
