There are some default tolerance values in many nonlinear analysis processes in the solver.

The solver precision ratio in solver settings (Main menu > Tools > Calculation & Mesh > Solver settings) allows modifying these default tolerances under Advanced solver settings > Nonlinearity.


The tolerances in the solver will be divided by the specified precision ratio.

For instance, a precision ratio of 10 means that all tolerance values will be 10 times smaller than the default setting (=higher precision).

Below you can find an example of a default tolerance (=convergence criterion) and how it can be influenced via the solver precision ratio.
