When simulating a model with beam elements, there is the option: render beam profile. I simulated the same model with and without the option and got very different results for maximum stress.

The model i used is from simulation course file: particle seperator.

for stress result:

without render: upper bound axial and bending

with render: axial and bending

would appriciate if someone could appriciate the difference in the max stress.

Thanks,

Michael
