Does it only go by the sample Point that is being displayed (is this based on closest Point?) or do you interpolate across the Cell that the object is in?

It actually uses the Runge-Kutta method, which computes a weighted average of slopes. The result is then the vector that defines the next integration point. However, the smoothness of the integral curve is most impacted by the characteristics of the vector field...If accuracy is not so important, you can use the curve re-sampling components to create a smoothe curve.

I should also mention that there is a balance between sample density and amplification of the sample vectors....Since the size of each integration step is dependent on the magnitude of the sample vectors, it's best if you scale the sample vectors so that they span roughly 1/2 of a sample point cell. This can be done by simply multiplying each vector in the sample vector list by some constant.

ok, I needed some time to understand what is it really for :D

But one thing is on my mind now - do you think is it possible to make aerodynamics analysis with your component ? I tried to do something that could be similar to aerodynamical tunnel, but I feel to stupid to do it :]

Hey, any effort with CFD is a good effort! CFD is really, really hard...

 

Currently, the Vector Components do not create the vector field, they simply provide the means to integrate them...Although the integrator is fairly bare right now, we're currently developing boundary, stopping, and interpolating methods.

 

I think we'll include some basic vector field creation methods (gravity, magnetism, etc...) but too in depth.

 

A link to a good, open source CFD enigine might be possible, though....

I think that interpolation is sooo great. and here is my LAME aerodynamics analysis. Of course I know that this does not have much with real aerodynamics, but it looks cool ;]

I forgot 

one surface is just a rectangular surface, and other is i.e. cylinder. (so its a cylinder in front of rectangular, planar surface)
