\\ *Numerical problems* or stability problems* may arise during analysis. If so, the log file should be reviewed. Information may be retrieved using the standard solver, available through Analyze > Set Analysis Options > Solver Options. Numerical problems should be fully resolved before analysis results are interpreted. When {new-tab-link:http://www.csiberkeley.com/}CSI{new-tab-link} Software encounters zero stiffness, a warning message will indicate that a small stiffness value has been assigned to allow numerical formulation to proceed. The model should still be checked to identify and remove the source of zero stiffness. {list-of-resources2:label=numerical-problems|drafts-root=Numerical problems drafts} h1.
