[Paraview] [EXTERNAL] Re: Calculating rms values using the Temporal Statistics filter

You should be able to use method (a) and then use the append attributes filter to combine the fields in the two branches into one dataset.

Subject: [EXTERNAL] Re: [Paraview] Calculating rms values using the Temporal Statistics filter

Hello all,

I would like to calculate rms values for my simulations.

For example, for the calculations of the axial velocity u'rms = sqr( ( (u')^2)_ave )

I first need to calculate the fluctuations, u'_x = u_x - u_x_ave.

I obtain:
1) u_x via the calculator.
2) u_x_ave using the temporal statistics filter

The problem that I am having is subtracting them from each other. I have tried in two ways.

a) calculating 1) and 2) in separate branches but then I cannot see the variables from each
b) calculating 1) and 2) in the same branch but then I do not have access to u_x because the statistical filter averages it out.


Any help is appreciated.

Best regards,
Janusz
