Hi all,

I am using Paraview for the visualization of my OpenFoam data. I would like to visualize a derived quantity which is

(dU_x / dx)^2 + (dU_x / dy)^2 + (dU_y / dx)^2 + (dU_y / dy)^2

Can someone please help me how to do that in Paraview ?

Thanks in advance !

Cheers
Chandi

In ParaView, you can use the "Calculator" filter to calculate new quantities, and "GradientOfUnstructuredDataSet" to calculate the derivatives.

See this ParaView state file (created in v4.1.0):

Alternatively,
you can try to use funkyDoCalc
or
you can write a codedFunctionObject (in C++) and execute it using OF4x's postProcess utility.
