Line Integrated Convolution (LIC) - Is it possible to implement/visualise it within CFX Post?

Thanks
Ted

You can generate the streamline field easily enough. I do not know of a way of randomly generating the noise image so you might need fortran to do this. And the line integral functions in CFD-Post work on all streamlines together, not each streamline separately as the LIC approach requires.

So this all looks possible, but will require some thinking and development. CFD-Post is not the most flexible package to do this sort of stuff in. It would probably be much easier in Tecplot, Ensight or Fieldview.
