Re: export variables to vtk or similar

[Fabian Braennstroem]

Hi,

    it seems that my last post did not arrive at the list...

    I got it working using the tecplot format writing the
    variables each to one file, deleting the top lines
    using 'sed', merge the files column-wise using 'paste'
    and adding a simple head for the tecplot format. Worked
    pretty nice, but is there a chance to write the
    variables in columns at once and remove the comments!?
