If you are using the 'Bolted Connections' then likely the problem is the rigid link that SW uses to model bolts. This connects only to the edge of the hole and if you look it up you will find that SW issues a disclaimer that stresses w/in about a bolt diameter are not actual stresses and, in fact, will be much higher. If you need to find out what is going on and you have a small enough part then I'd suggest modeling up the bolt, nut, and washer. You will have to manually apply a pre-load.
Thank you for your answer. yes I used bolt connection to simulate the link including also the pre-load. I see that for the bolt connection SW compute correcly the surface of influence On the plate. If I don't succced in soving this problem for foundation bolts, rightly I can modelling the exact foundation bolt only on the most stressed surfaces to not load too much the solver.
thank you for your advice
