If 200 plane diffraction of fcc cancels out that of 100, why do we still see that of 200?

I am trying to understand the systematic absences that occur for certain symmetry. The explantion above was given for fcc but I would have thought that both of them would not be seen if the above...

Why does ITO have a band gap (even though optical) and is yet a conductor?

What is the difference between band gap (for semiconductors and insulators) and optical band gap?

fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.

Arena simulation - how do i model the following model in ARENA (see description) (new to ARENA)?

Hello, I'm fairly new to ARENA and I have the following problem: I have two queues in which, in each queue, a different order type arrives (both having an arrival rate of exponential 10). Order...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...
