Hello, I was wondering if there is a general rule for setting sensor to rays ratio in simulation? I have lowered sensor resolution and it seems that results run to infinity.

Hi @Marian, of course if you increase sensor sampling, there is more pixels in the sensor that integrate rays and obviously you need to propagate more rays. So increasing sampling will increase convergence time.

Hi, but why does it change my result in such a manner? The three areas above are the same locations inside the glazed cabin with different sensor settings. How are we able to say our resolution is good?

I am normally a structures FEA user, so this is a bit of a new field for me. When I do mesh sensitivity studies in mechanical, my results usually do not change dramatically like this. Eventually, they would settle on a certain value.
