[Paraview] [EXT] Re: How to detect element type inside Programmable Filter

[Dennis Conklin]

David,

Thanks very much, I’ve sorted through my stuff and found out what VTK thinks each of them are.   Since EXODUS limits each block to a single element type, it never occurred to me to test the type of an individual cell, I was sure there would be a block level cell type.

Thanks again

Dennis

Shell means locally 2D and Truss means locally 3D?

def process_block(block):

    #print dir(block)

    #print dir(block.VTKObject)

    print block.VTKObject.GetClassName()

    for x in range(0,block.GetNumberOfCells()):

        #print dir(block.GetCell(x))

        print x, block.GetCellType(x)



for block in output:

    process_block(block)
The printed cell types correspond to:

There is probably a macro somewhere to get a GetCellTypeAsString() but easy enough to do in the filter.

David,

Yes, but I am more dense!!


print block.VTKObject.GetClassName()
prints out vtkUnstructuredGrid,  which I already know.

Within my UnstructuredGrid, some blocks are hex elements, some blocks are shell elements and some blocks are truss elements – that is what I am trying to detect!

I am more persistent (and more dense). :)
