[Paraview] Python calculator

[Fred Fred]

Yes it helps, thx.
But what does the 2 first fields mean?
For instance I would like to select the name of the vector field from an argument of the python script, should I do this:
  filter.VectorVariable = [options.name, 'velocity', '0', '1', '2']
or this:
  filter.VectorVariable = ['velocity', options.name, '0', '1', '2']

The way to specify a vector variable is not entirely intuitive:

filter.VectorVariable = ['velocity', 'velocity', '0', '1', '2']

Hope that helps,

Peter.

I a trying to compute the velocity magnitude but there are some thing I did not well understand:
First, what do the 3 arguments of VectorVariable mean?

  filter.VectorVariable = ['velocity','velocity', '3']


Second, what is wrong here:

  filter.Function = 'mag(velocity)'
