Is there similar result between simulation and reality? While designing an aircraft and analyzing it using simulation software, one result comes out. Is what occurs on the aircraft in reality similar to the result as given in a simulation?
Yes, usually

Simulators are pretty accurate, at least for the specific things they're programmed to measure and account for.

For example we have a pretty good idea how airflow works, so airfoil/wind tunnel simulation is very accurate. We also have quite good ideas of how materials react, flex, break etc, and can model them pretty accurately.

However

No simulation is 100% accurate: there is always potential for things in the "real world" to happen in a way we either didn't account for, or weren't expecting.

For example sometimes manufacturing flaws mean a material breaks in a way we weren't expecting, or an external influence changes the way something happens. We also don't have a 100% understanding of aerodynamics under all conditions.  This is why we still need real-world testing. There are also circumstances we've never encountered and therefore can't be certain of: eg aircraft are designed to handle around 150% of the force of the strongest known/experienced turbulence, but we can't be truly sure that this hypothetical 150% turbulence would act as "regular" turbulence, merely 50% stronger

In short: yes, the results will be similar, but they will not necessarily be identical, depending on exactly what you are testing.
