Meshing Notes and Comments A fea solution may give better results for short, tall beams than beam theory. This is because of St. Venant’s principle and because short beams are dominated by shear Some meshing comments follow FEA is about attention to detail, and understanding what you are modeling

Where should stresses, deformation, and attention be placed?

Meshing of Odd Shapes Nodes must be at corners for all linear elements For test problem, better or other options were to use rectangular elements or increase the order of the element.

Triangular elements

Rectangular elements

The best mesh This mesh has sufficient elements around the hole and at the small feature, but could have less elsewhere.
