Hello!

I had a question regarding the FEA analyses of a Lug, When I load the lug with a pressure force at the pin hole and then apply body forces to simulate 750 kg under gravity, I end up with an error of singularity as shown in the pictures. But instead of the body force when I apply fixed support on the body, it seems to work. So I am guessing that it is due to the horizontal forces produced from the pressure forces. So I wanted to ask what would be a good way to eliminate those without having much effect on the results or if you could suggest another way to carry out this kind of simulation, that would be awesome too!

Thanks,
