Mesh Independence
In StressCheck the modeling errors are treated separately from the errors of approximation so that the analyst can validate the model and verify the result independently. Other FEA programs typically have hundreds of elements where StressCheck would have just one. To us a quadrilateral is a quadrilateral; why would you need more than one?  StressCheck treats the attributes of the element separately from the topology of the element unlike any other code. Switching between heat transfer and elasticity, for example, does not require changing elements or remeshing. That's hierarchic modeling.

With hierarchic modeling our formula is simple:

1 Mesh + 1 Mapping + 8 Polynomial orders = Guaranteed Reliability
