This driver is built-in by default

MDAL supports reading of unstructured grid (mesh) data from NetCDF files based on UGRID format. The UGRID conventions are an extension to CF conventions to describe hybrid 1D-2D-3D meshes and unstructured mesh topology and geometry. UGRID is used for example by the Delft3D Flexible Mesh Suite, FVCom/VisIt, ADCIRC and BAW’s unstructured grid tools. Additionally, MDAL supports detailed 1D network topologies and geometries.
