low load beams ... difference between 2d and 3d analysis

[meccanicamg]

I've put in circles without possibility of moving or rotation... but I still tried to make two inks even in the 2d but it doesn't change much as deformation.

ps use algor not inventor but will be very similar

I don't remember anything about algor anymore, I used it a few times at university. :frown:

here is a sequence of analysis made with fem and method 2d ... I have some problem with concentrated loads because they create a concentration of efforts that, in reality, is not truthful. the only solution I have found and choose more neighboring knots and subdivid the force for the number of chosen knots ... it seems a somewhat empirical method but it works
