I am about to defend my thesis and part of my presentation would involve results and conclusions from my two unpublished works. Personally, I am confident about the results and conclusions. My advisor is yet to work on the drafted manuscripts so she is familiar with the results but has not critically thought about the numerical methodology implemented or any other issues with the results. I have presented the results in different conferences, but again, no one really asks questions at conferences. These were not conference proceedings, so no peer review has been carried out yet.
So, I was wondering, what will happen if the committee (who are experts in my field) sees a potential fault with my work which I might have overseen? What if the potential fault undermines the works I have done? Will that lead to a negative outcome in my defense?
