Asme section viii div 2 and api 6a require a local failure (triaxial stress) at every node is checked. This means the sum of the principal stresses must be less than 4Sm (For linear fea).

Is there a more efficient way to export these stresses or perhaps create a custom stress plot?

Exporting tabular stresses through simulation on large models can take upwards of 8 hours for each principal stress. This is not very practical.

Thanks..
