Unstructured data to structured
 

Hi, I am new to this software, and have imported an Ensight file which gives me data objects which are unstructured. I would like to perform some operations in Paraview (ie extract subset) which can only be done on structured grids. Does any one know if it is possible to a)change the Ensight export format of the data to structured or b)go from unstructured to structured data within PV? The Ensight file was created in EDEM.

Thanks!!
