  The warnings seem to suggest that the tube (or one of the parts) is not constrained fully and it has rigid body motion. Can you show images for the boundary conditions you applied. nThere is also an error in your model. It could be high element deformation error. can you send an image of this error message?.

  Common modeling check to identify rigid body motion constraints:n1) Apply a uniform elevated temperature load to a model. A properly constrained model should not generate any stress under a free thermal expansion loading condition. n2) Modal analysis will frequently expose the problem bodies of an improperly constrained static model. Zero frequency modes will be found for every possible rigid body motion. Animating the mode shape will graphically illustrate the direction in which the model is free to translate and/or rotate.n
