From 3D dfsu file

For a 3D dfsu file the node values and element values in the dfsu file are saved in separate shape files.

The following files will be generated:

1.       A shape file (and accompanying index, projection and DBF files) for each selected layer containing the level of the nodes by a point feature layer.
(naming convention: globalname_Nodes_Layerlayernumber.*)

2.       A shape file (and accompanying index, projection and DBF files) for each selected time step and each selected layer containing the selected ele­ment values by a polygon feature layer.
(naming convention: globalname_elements_Layerlayernumber_time­stepnumber.*)
