	The postprocessor NCCUTOUT may help users to reduce the size of result files in order to save disk space and computation time in the subsequent processing steps. It cuts out data of UGRID compliant NetCDF files of the area type. In UGRID metadata language the files have to have at least one mesh topology variable with the attribute topology_dimension = 2. The cutting is typically defined by a polygon. The elements inside of the polygon get extracted to the result file. </P>		The postprocessor NCCUTOUT may help users to reduce the size of result files in order to save disk space and computation time in the subsequent processing steps.

	But the cut out area can also be defined by two or more polygons which need not be direct neighbours, s. Fig. 2. Though the results may look like seperate spots of a location grid they share a common mesh topology.</P>		But the cut out area can also be defined by two or more polygons which need not be direct neighbours, s.
