By default, the axis system for application of contact forces between a pair of contact elements is based on the instantaneous positions of the elements at any given time. In some rare circumstances, you may wish to specify that the line of action of the contact forces remains constant, and be based on the initial positions of the contact elements. An example might be a static analysis for which solution convergence occurs, as an equilibrium configuration is difficult to attain due to the nature of the contact interaction. However, the constant axis system option should rarely be invoked.
•*CLASHING SOLUTION is used to specify solution parameters associated with clashing.
