mi38.feb
This model demonstrates the application of the fixed normal displacement constraint on a shaft, with the constraints prescribed at locations of bearing support (at one end, and at the middle of the shaft). A transverse load is applied using a surface traction on the free cantilevered end of the shaft.

This model demonstrates the application of surface force on a cantilever beam. The force vector is prescribed at one end while the other end is fixed along all displacement degrees of freedom. The force is distributed as a uniform traction on the prescribed surface and does not change with the deformation.
