6.5 Contact iterations in ABAQUS/Standard

Products: ABAQUS/Standard ABAQUS/CAE

Benefits: Contact severe discontinuity iterations are executed faster for frictionless static contact problems. Contact iterations can be especially effective for the solution of large linear elastic contact problems with many severe discontinuity iterations.

Description: Contact iterations are executed without reassembling and refactorizing the global stiffness matrix.
