Is my model converged? Can I trust the numbers?
It is assumed that the model has been correctly built, that there are no poor constraints, loads and overall approach is good. We are just left with the problem of trying to determine if the stress numbers are good.
There is no single output that states the answer is good. Besides, the software doesn’t know what your objective is. The ‘goodness’ of an answer requires the user to review a variety of information ‘in the round’ in the context of the objective.
A simple ‘plate with a hole’ model and a simple ‘L’ shaped bracket are used to show that converged answers can be achieved from a model with poor constraints and that the actual answer is not an exact number.
The Single Pass and Multipass Adaptive methods are compared.
