孤立子是数学和物理上最美丽的存在之一(待续)
照Guokr的同学说——卖萌是维护互联网和谐的重要手段！
空间分布倒是让人很高兴，另外美国的分布也更加均匀了。总数上还是太少了，争取参照Analytics改进一下
A tutorial case of the Gerris CFD package. A right heading flow with U=1m/s enters the domain from the left boundary. Upper and lower boundaries are frictionless solid walls. The right boundary is a simple outlet with zero pressure gradient. Vorticity street is generated by the instability of the trailing vortices behind the half cylinder.
Recently I updated to ubuntu 11.10 – for no good reason. Now I think about it, the reason should be I forgot the golden maxima “don’t ‘fix’ it unless it is broken”. After getting lost and tortured by the fancy interface, and found there was no way to roll back by package uninstallation. I reinstalled [...]
Just one default case coming with the model. The domain is a portion of East U.S. Coast. 1. two-dimensional velocity field (not scaled by magnitude, just to show the directions) 2. three-dimensional velocity field (scaled by magnitude) 3. sigma coordinate
