Vorticity Confinement

GeForce GTX 1080 or higher recommended.

Boundary Condition 1, ReynoldsNumber = 1000, dt = 0.0005, VorticityConfinement is Disable
```
python main.py -re 1000 -dt 0.0005 -vc 0.0
```
Press V key switches the flow visualization method. dt is automatically determined even if not specified, but should be small for divergence.
Boundary Condition 2, resolution = 800
```
python main.py -bc 2 -res 800
```
Boundary conditions can be specified from 1 to 6
Boundary Condition 3, ReynoldsNumber = 10^8, resolution = 800, VorticityConfinement = 10
```
python main.py -bc 3 -re 100000000 -res 800 -vc 10
```
Help
```
python main.py -h
```
for CPU
```
python main.py -dt 0.0005 -cpu
```
