[Paraview] streamfunction

[David Larsson]

Dear Paraview users,

Has anyone ever calculated the so called stream function (grad^2 (stream function) = -vorticity, set up as a Poisson equation) in paraview? I seem to find old posts in the mail list regarding a streamfunction filter, but I might be wrong (since I can't find any in recent versions). Computing vorticity is quite straight forward, but has anyone continued into streamfunction visualization? Or is the only way going through e.g. a programmable filter?

Thanks for your help,

/David
