single points in solidworks simulation

[Mauro56]

Good evening to all
I happen frequently, using the fem simulation package of solidworks, to find singular points in the structure, where stress reaches high values and exceeds the resistance of the material. I think they are unique points because in the complete structure the stresses are all much under the critical value of yielding. I attach a design, where I have a structure loaded with forces applied on the colored flanges that are seen in the first design and the fixed bond on the square flange below. when I perform the fem analysis the maximum of the stress I find it at the point indicated in the second drawing, in an area that is discharged.
I would like to discuss this issue in order to solve this problem but I do not find tutorials or books or anything where I can deepen this aspect. sw tutorials and those on youtube are very generic and face very simple cases. Can someone tell me where I can find more detailed material about sw simulations? Thank you.

more than solidworks simulations, I would deepen the theory of finite element analysis. In general, this problem is found close to "rapid" variations in geometry. I'm sure if you change the geometry locally, you would have stress values in line with your forecasts.

Unfortunately I cannot improve the situation with the changes in geometry, indeed, in some cases for example by replacing a living edge with a fitting, the situation still worsens, without getting the hoped results. thanks for the interest, sooner or later we will find the solution
