If you select the 'Warning' option, the solver pivot problem will appear as a warning message. And the solution will go on at the solver level.

22.06.2018 · In ANSYS when a negative or zero pivot value is encountered, the analysis may stop with an error message or may continue with a warning message, depending on the various criteria pertaining to the type of analysis being solved.

24.02.2020 · Solver pivot warnings or errors has been encountered during the solution. This is usually a result of an ill conditioned matrix possibly due to unreasonable material properties, an under constrained model, or contact related issues.

Jun 23, 2018 · The pivot or pivot element is the element of a matrix, or an array, which is selected first by an algorithm (e.g. Gaussian elimination, simplex algorithm, etc.), to do certain calculations. In the case of matrix algorithms, a pivot entry is usually required to be at least distinct from zero, and often distant from it.

"There is at least 1 small equation solver pivot term (e.g., at the VOLT degree of freedom of node 66) which may indicate a numerically unstable model.
