2. 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

3. Basic Trailer

4. Where should stresses, deformation, and attention be placed?

5. Where should stresses, deformation, and attention be placed?

6. 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.

7. Triangular elements

8. Rectangular elements

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