Problem:

When analyzing a model the following occurs:

--------------------------- Confirm --------------------------- The load case did not converge. Do you wish to continue iterating? --------------------------- Yes No Cancel ---------------------------

Should it continue to iterate, or not?

Solution:

Yes, generally the default number of nonlinear iterations = 5 (in version 6.0 or earlier) is adequate for most models but for models with large gaps and friction it is not uncommon for convergence to occur after 20-30 iterations particularly with the thermal, wind and earthquake cases being analyzed in one model.

If the analysis did not converge within the specified number of iterations, a confirmation dialog will be displayed requesting whether or not to continue iterating. A "yes" selection will allow the user to specify an additional number of iterations to perform. A "no" selection will display another confirmation dialog requesting whether or not to display the error log file (*.LOG). Press OK to close the &rsquoEquivalent Linear Analysis’ dialog.

If at least one load case converged, the analysis results may be examined using the options found in the Result menu regardless if other load cases did not converged successfully. In the case in which the analysis did not converge, an error message will be displayed after selecting any Result menu option (except Filter Criteria) indicating that the analysis did not converge. In addition, a double asterisks is printed before the combination names in the Code Compliance Combinations listing and Other User Combinations listing in the Load summary sub-report indicate that the analysis results for those marked combinations did not converge.
