Cool FEA Tips:
1. When to Perform Non Linear Geometric Analysis?
The rule of thumb is if the largest displacement in your model is greater than 10% of the largest dimension of your
model then you should run a geometric non-linear analysis.
2. How to perform equilibrium check?
Double check your applied loads with your reaction forces. Use simple beam bending stress equations to verify bending
moment stresses are in the ball park. Perform internal force calculations at various cross sections of your model.
3. What are the basic design checks?
Check for unconnected regions. Check for coincident nodes to make sure mating surfaces are connected as you intended.
Also perform a free-edge element check to ensure elements are connected properly to each other. This is most useful
when checking your 2D shell elements connectivity to each other. A highlighted free-edge will quickly indicate any
edges that are not 'welded' or joined to any other element.
Make sure you have properly restrained all 6 rigid body modes. You can do this by having a minimum of three points on
your model constrained with one xyz fixed node, one xy fixed node and one z fixed node. Also understand that stresses
will approach infinity at sharp corners and boundary condition nodes. The finer the mesh at these locations, the higher
the stress.
4. How to reduce the size of complex simulation designs and save time?
Some of the options
1) Use of symmetry
2) Instead of uniform mesh, use coarse mesh at non-critical area and dense mesh at critical areas
