Dear all, dear Prabhu,
the following question may be slighty off topic but I was hoping that
somebody in the audience may have tried to do something similar before
and could give some advice. If not, just ignore this email and accept
my apologies, please.
We would like to calculate the circulation (=the line integral of
scalar product of velocity and tangent vector of the line) of the flow
around a torus-shaped object. We have the data in VTK (obviously using
mayavi to look at it ;-) ) and are wandering whether it might be
possible to compute the circulation with VTKs help.
Some background information:
The actual simulation is carried out with a somewhat complicated
locally refined rectangular mesh (and we have not implemented this
and are neither very confident in decoding the data structure) but
we have managed to import the data to VTK. It would therefore be
immensely convenient if VTK could compute the circulation as it
knows the velocity field anyway, and can carry out linear
interpolation between the provided data points (something which
would be that easy to code by hand for this example).
It may be possible to use a square path around the torus shape object
(instead of circular path) if that makes the problem any easier to
handle.
Thank you for listening,
Hans
