3nd Step

I should do the following things as soon as possible:

1. Add the user-interface*

2. Several particle streams towards different directions when meeting the vessel branches.

3. Control the suitable injection direction so that it will not be stucked from the beginning till end.

Now I have initial model about 4 particles lines, and with two small size, two large size, and which initial position is relative to the axis direction's vertial axis, and arranged orderly. The effect is not bad, but is not that satisfied. I use four colours to show the result.

The next step:

1. the fluid will not back, so control the angle!!!!

2. the speed!!!!

I have achieve the basic idea of FLTK....

Now testing...

The next step is to model the particles in a specific situation!!!!!!!!!

No mass spring????????? is that OK?
