1 year ago This is the vorticity field after 10,000 steps:
The mean velocity (ux) changes from 0.18 at cycle 0 to 0.024 at cycle 9999
In this problem, I used periodic boundary conditions, so the flow will slow down with time as the fluid hits the cylinder. The result is expected.
You may wish to implement inflow/outflow boundary conditions to have sustained motion
Hi, I noticed that while the simulation continues the values of the flow field are getting smaller and smaller. That is the case if I use e.g. 10K time steps of the simulation. Why is that so? Is it meant to be this way? I wanted to use this data in my project related to flow learning via neural networks and values which are becoming very small is somewhat problematic.
