Hello Karen,
yes, you are right. In this file a cell has only 4 nodes, because this
is a 2D example. You can see this at the word "quad" defining the cell.
This stands for quadrilateral, hence 2D. In 3D one would have "hex" for
hexahedral. For tetrahedra one would have "tet".
Here you can find the general documentation of the UCD file format to
read more about the different types of cells:

Best Regards,

Hi Markus,
I'm looking at circle-grid.inp right now, and it seems that the
elements have 4 nodes (tets) or am I slightly confused...
Thanks you so much for your help,
Karen
