If your simulation includes only small-sliding, frictionless contact, select
Allow small sliding, frictionless contact changes to improve
performance. Otherwise, select Do not allow contact changes.
Small-sliding, frictionless contact is intended for use with the
small-sliding approximation or tied surfaces in surface-based contact. It is also used
with the small-sliding formulation for contact initialization in general contact. For
more information, see Defining Surface-Based Contact in Implicit Steps and Defining Contact Initialization.

From the Matrix storage options, specify one of the following
options for the matrix storage and solution scheme:
Option | Description |
---|
Solver default |
Uses a matrix storage and solution scheme chosen by the Abaqus solvers to store the stiffness matrix. |
Symmetric |
Uses the symmetric matrix storage and solution scheme to store the stiffness
matrix. |
Unsymmetric |
Uses the unsymmetric matrix storage and solution scheme to store the stiffness
matrix. |
For more information about these
options, see Matrix Storage and Solution Scheme in Abaqus/Standard.
