However, I need two scalar field.
How can I do?

please help me, I cannot find any tutorial

madhukar_m_rao · April 22, 2012, 11:25

You can give multiple scalars in your file; each with its own name.

See the vtk website: http://www.vtk.org/VTK/img/file-formats.pdf

diedro · April 22, 2012, 12:56

hi,
thank you

now it works..with scalar

however it does not work with vector fields:

Code:

           0.00000
VECTORS velocity float
           0.00000           0.00000           0.00000
           0.00000           0.00000           0.00000
           0.00000           0.00000           0.00000
           0.00000           0.00000           0.00000
           0.00000           0.00000           0.00000
           0.00000           0.00000           0.00000
           0.00000           0.00000           0.00000
           0.00000           0.00000           0.00000
           0.00000           0.00000           0.00000
           0.00000           0.00000           0.00000

do you see something wrong?

thank you
it is very important

madhukar_m_rao · April 23, 2012, 02:15

The vector components seem to be all zeros. vtk has nothing to plot, if that is the case.

diedro · April 23, 2012, 05:13

Dear madhukar_m_rao,

I do not have only zero, I copy only few line of my input file. Indeed my error is

Code:

Generic Warning: In /home/utkarsh/Kitware/superbuild/paraview/src/paraview/VTK/IO/vtkDataReader.cxx, line 1382
Error reading ascii data. Possible mismatch of datasize with declaration.

diedro · April 23, 2012, 10:25

I get it
it was a my error in plotting data,

as the error message says.

thank all

diedro · April 30, 2012, 11:03

dear all,
as you can see I get it.
However, How can visualize both of them at the same time?

thanks a lot
