Hello all & a happy new year...
Take for example the 13th one, where the primary field variables are
velocity components U, V and pressure P. After solution is achieved per
each time step then results are printed in GMV, VTK, etc...
My question is: how to print those results in vector form (especially the
velocity components in one vector u={U, V, W} instead of seperate scalar
results)?
Helpfull hints and ideas are greatfully acknowledged :)
regards, Vasilis

GMV has facilities for taking D scalar variables and displaying them
as components of an R^D vector; IIRC Tecplot does as well and I'd be
surprised if Paraview etc. didn't.
If there's some specific output format that requires those vector
components to be associated a priori, there's probably nothing to be
done about it except to add an API for doing so and modify the I/O
class to handle it.

Mostly i use Paraview to visualise results through VTK or EXODUS2
formats...but since the velocity field variables (U, V) are independent
scalars they cannot be used directly as ONE vector field variable!
any hints?

In Paraview, you can use the calculator filter to convert scalars into vectors. See here: https://visualization.hpc.mil/wiki/Paraview_Calculator (at the bottom) Hope this helps... -Norbert > On Wed, January 7, 2009 02:16, Roy Stogner wrote: >> On Wed, 7 Jan 2009, va...@me... wrote: >> >> >>> Hello all & a happy new year... >>> >>> >>> Take for example the 13th one, where the primary field variables are >>> velocity components U, V and pressure P.

You are right, although the URL appointed doesn't work! Paraview calculator filter does work for the job! many thnx Vasilis 2009/1/7 Norbert Stoop <no...@st...> > va...@me... wrote: > > Mostly i use Paraview to visualise results through VTK or EXODUS2 > > formats...but since the velocity field variables (U, V) are independent > > scalars they cannot be used directly as ONE vector field variable! > > In Paraview, you can use the calculator filter to convert scalars into > vectors.
