Can't seem to get it right

Hi,

 

I'm trying to test if a part that I design is strong enough for what I need but I can't seem to do an FEA on it. I tried making it one single part and I got a message that the model is too unstable, so I activated the soft springs options, but nothing. It told me that the displacement was too big and didn't give me any result.

 

So I started again, this time make the model out of sepate parts and assembling them. I put in all the fixtures and forces, but now it gives me another error (picture). It suggested using the direct sparse solver, which gave me the "not stable" treatment again.

 

The main objective was to see if the model is strong enough and if the welding is.

 

Help would gravely be appreciated
