CFD-Post isosurface animation

Tkjeong · May 8, 2014, 21:30

Dear everyone!

When I use isosurface(volume fraction=0.5) in CFD-Post to make an animation, it just shows interface change between water and air.
But I want to get more realistic water flow animation like this(http://www.youtube.com/watch?v=7RYvWKRpDII).

how can I make the realistic water flow animation???

Thx

The colour is simply the fluid velocity.

But I suspect you are asking how they get all the fine flow detail in the result. This is an FAQ: http://www.cfd-online.com/Wiki/Ansys..._inaccurate.3F

With the main issue being mesh. You need a high quality, fine resolution mesh to get detail like that.
