alfonms,
You need to check the displacements and rotations in T1 only case. There is no weight involved. The T1 only case will show the displaced location of nodes under the given temperature profile. Since weight is not involved you should not get huge vertical displacements.
In new model, the displacements are applied at restraint points/nodes that were selected earlier as CNODE (new model implies to the same Caesar file with new name and temperature profile applied to complete system along with restraints).
