13.218.1. Other Applicable Sections

Hydrodynamic Bearing describes the governing hydrodynamic lubrication equations used to form the element matrices and vectors.

 

13.218.2. Assumptions and Restrictions

The element normal must lie in the global XY plane as the bearing length is along the global Z-direction.
