Basing on the precision calculation method used in Algor, how do I know when the results have converged? the precision ranges from zero (best) to 5 (worst), but what is the standard acceptance of precision that the results should be based on so that I won't have to do mutiple runs with finer meshes to determine that the solutions have converged. Thanks.
Precision does not consider the "significance" of the stress for which the precision is based. For this reason, a poor precision may be indicated in a region of the model that possesses insignificant stresses. I mesh convergence study requires no less than three different mesh sizes refined in the regions of interest to determine if the stresses converge or continue to increase which would indicate a singularity. Singularities are addressed by altering the original geometry to include fine details such as filets or rounds or by applying loads or boundary conditions distributed over a consistent area instead of a specific single node.
