I am having problems with a cantilevered pipe analysis. In my recent attempts at modeling this situation i have been cutting a 0.01 inch layer from the load region and the restrained region. After doing this, I was able to select those regions in COSMOS. Is this an appropriate method? I was needing to do an additional analysis that would simulate the pipe being clamped/fixed with 6 bolts that are 60 degrees appart. Can anyone recommend a good way in doing this? So far i have made small cylinders that are tangent to my pipe. Unfortunately, I dont think this is the best method.
