Any interesting experience on the use of the MCNP Monte Carlo N-particle transport code at nanometric level?

Several simulation studies show that the MCNP code fails when dealing with detailed physics at nanometric level (e.g., when modeling B4C nanoparticles in neutron shielding materials).

Is there any test to determine the cardiovascular risk of patients with obesity? from the perspective of obesity?

We found tests to determine cardiovascular risk taking into account lipid profile, blood pressure, age, history of diabetes, other laboratories. But when weight is involved, there is a paradox. I...

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...
