[Paraview] Data structure type

[Moreland, Kenneth]

Chris,

Ultimately to represent your data in the way you describe, you will need to store it in an unstructured grid. Even though your data are regular in the X and Y directions, the structured data types will insist on connecting the points of the cells, which you explicitly stated that you do not want. The unstructured grid does not have this restriction. Although it can (and usually does) share points across cells, it does not have to.

Thanks Dave, I’ll take a closer look.
I think I’m still a little confused about cell based data versus node based data at the top and bottom of the cell ….

I found this which was generated with Paraview, so I know it can be done ☺

Try vtkStructuredGrid and the Cell Data to Point Data filter.

Good day.

I’m looking into Paraview for 3D visualisation of modelling results from an integrated surface water/groundwater model.

The model domain is discretized as a uniform rectilinear grid; calculations are performed for the grid centroids.
However, the vertical extent of a grid cell is described by a top and bottom elevation, constant over the cell.
This results in a staggered arrangement of cells (kinda like Lego blocks) in cross-section view:

NOT:

I’m wondering what data type/structure I would use for this kind of data?

Also, is there an easy way/filter in Paraview to re-project/interpolate the centre based (const) elevation data to the corners/nodes of the uniform rectilinear “horizontal” grid, which would allow for a display as shown on the right (instead of staggered)?

Thanks a lot,

Chris
