The Gradient of Unstructured DataSet does provide a vorticity computation option but as the filter's name implies, it is only valid for grids that derive from vtkPointSet (vtkStructuredGrid, vtkUnstructuredGrid, vtkPolyData and maybe vtkLabelHierarchy).<br>

You can use the 'ComputeDerivatives' filter and select 'Vorticity' as the output vector type.<br><br><div class="gmail_quote">2010/10/26 David E DeMarle <span dir="ltr"><<a href="mailto:dave.demarle@kitware.com" target="_blank">dave.demarle@kitware.com</a>></span><br>

Then you should be able to calculate "manually" the cross product. <br>

Hi,<br>
<br>
I have some transient Ensight gold data (cell data). I want to calculate<br>
vorticity for each time step. I checked the calculator option in paraview.<br>
there i see dot product tab but not cross product tab. Can anyone please<br>
help me with it. I am very very new to Paraview<br>
<br>
Kind Regards<br>
<br>
