1. Flow over a wall-attached squared obstacle:
Animation of transient flow over obstacle (top)
Averaged field solution of x-velocity (bottom)
Transient bahaviour of globally averaged velocities and mass. Velocity is area averaged over whole domain, mass is summed up. Flow still not in steady state conditions!
Flow around obstacle at wall Obstacle transients
Obstacle flow mean

2. Flow around a centred squared obstacle:
Animation of a flow around a central squared obstacle with vectorplot. Flow not fully in steady state conditions. Averaged field solution of x-velocity (not fully steady state conditions)
Flow around an centred obstacle Flow around obstacle

3. Channel flow (with inviscid and viscous walls):
Animations: start-up phases of channel flows:
Top     : channel with inviscid walls
Bottom: channel with viscous walls
Mean field solution at steady stade conditions. Average calucated over dt=2.0e-2sec Transient bahaviour of globally averaged velocities and mass. Velocity is area averaged over whole domain, mass summed up.
