Hi Peter, thank you for your answer and yeah you are right I didn’t even realise that. Since the value is still rising with smaller element size, then how would you go about having a conclusive value? Would extrapolation down to zero in element, be a good way to do it or is there a better way to go about this?

Nodal stress with extrapolation

Also since we are only interested in the cars upright for results, we have decided to make the shaft slender and also adding a fillet to that slender region. Keep in mind I haven’t actually done a convergence analysis on this one yet.
