I am trying to model a large pump tower that is supported by a composite pipe section as shown in the attached image. One 24" OD pipe inside a 42" OD pipe with concrete grout between. Can I model this in RAM Elements CONNECT Edition?

I'm getting a "Huge Displacements" warning on a simple RAM elements model. All all accounts, the model appears stable and the maximum nodal displacements are very very small, less than .1". Any suggestions on what might be causing this warning?
