Hallo everybody,
Until now I dealed with RANS only considering wind flow in an empty domain and getting the pressure coeff on the facade walls. I manage it  after a lot of learning. Now I need to find out maximum and minimum pressures on the same walls. Is it too complicated? What I should know? Where I can find it? When I tried I was confused with the following: total time, time step and initial time? I don't have a hint  what values should be there.Thank You people! |

The problem solved with LES is not only depending on the good mesh resolution and proper time step, but you need to face a real time-dependent case which is really different from RANS. Thus, you need to wait until the numerical transient is finished, then sampling the fields to perform statistical analysis |
