Stress river,

Yours is very dangerous advice. Clearly you are inexperienced and misled.

Without proper training, how could you possibly know whether your FE model is correct, or that you have identified the peak stresses for instance ? It is not simply a matter of looking at a nice colour plot. The mesh density, boundary conditions and nodal locations are paramount. Do you know this ? If so, how did you learn it if FE knowledge is not necessary ?

Your strap line ... Know what you are doing! is a bit of a joke.
