UMMIP Stage 0: Michelstadt, no thermodynamics

Description

In this stage, a steady-state flow over a complex urban geometry is simulated. For this purpose the so-called Michel-Stadt scenario is used for which reference measurement data is available from wind-tunnel experiments (c/o University of Hamburg, Germany). The atmosphere is considered to be neutral (no thermodynamics) and the simulations are to be performed until steady state is reached.

Model parameters:

• Grid spacing:
• Background wind: Constant inflow wind profile (see input data)
• Roughness length: 0.01 m
• Lateral boundary conditions: arbritrary (cyclic or non-cyclic). For cyclic boundary conditions, a sufficiently large precursor domain should be considered.
• Surface boundary conditions: Local Monin-Obukhov Similarity or similar
• Further settings:
