[Paraview] Face Data on vtkUnstructuredGrids

[Parker, Andrew (UK Filton)]

Hi,

 

I have to be honest so far there has been no solution/suggestions to the problem I posed.  I am particularly interested in the access pattern I described, but also the ability to be able to add a scale to faces of a 3d unstructured mesh, which I can then cut.

 

Any help would be great, I should imagine this is of interest to a lot of people.

 

Andy

I have the same problem 
I dont know how to export data on surfaces like wall faces through vtk , as vtk is a bulk reader

Suppose I want to show data on wall zones,inlet zones,outlet ,  no idea how to show that.
IF you solved ur problem please post the solution

Hi,

 

I already have an established reader that reads in our bespoke format and converts it to a vtkUnstructuredGrids so that I can view it in Paraview. Furthermore a filter then reads in a solution file in a bespoke format and shows the cell data from the CFD solution. This works great, happy days.  However, I now need to show data on the faces on the vtkUnstructuredGrid, a metric.  I have two problems, no idea how to set this given the above setup, and two, to compute the metric I could do with the following type of access:

 

Loop over all faces of vtkUnstructuredGrid

                

                Get the face centre

                Get the Left cell centre

                Get the Right cell centre

 

                Do some stuff…..

 

                Set a scale on the face to be a number based on the stuff

 

Finish

 

I have no idea how to access the vtkUnstructuredGrid in the above to pattern???


Can anybody help, it would be very useful… examples more than welcome.


Cheers,

Andy
