Summary

The fluid flows in from velocity-inlet-5 (red part) at 1 m/s and from velocity-inlet-6 (green part) at 3 m/s, and flows out from pressure-outlet-7 (blue part). A No-slip condition is set to the channel wall, and the calculation is performed as a 2-dimensional problem with a single mesh in the Z direction.

The calculation is performed up to 10 seconds later.
