my query for modelling of above grade pipelines. For one of our projects under implementation, we need to model above grade pipelines lying on sand without any additional supports i.e. bottom of pipeline is touching sand ground througout the pipeline length. Please answer my following queries:

1. Since Soil modeller available in Caesar can not be used for above mentioned scenario, what is the alternate method for modelling these pipelines.

2. In case we have to use supports at uniform distance, what shall be the maximum distance to match continuous support requirements as per above mentioned scenario.

3. How shall we define soil stiffness in your proposed alternative?

Your early reply on above queries will be highly appreciated.
