Solver pivot errors are one of the most encountered errors in ANSYS® analyses. Sometimes, these errors can abort the solution completely. Here, we explain how to manage the solver pivot errors and checking in ANSYS® Mechanical analyses.
Sometimes, when you are building your model in ANSYS® Mechanical, you can build the model underconstrained and contacts can be under-defined. These issues can lead to situations of ill-conditioned matrix operations in solver which will produce solver pivot errors. You can manage these errors with Solver Pivot Checking options.
As you see in the screenshot above, it is very easy to do. Click on ‘Analysis Settings’ then select an option from the ‘Solver Controls’ section.
