Help! ANSYS ICEM

Chungang CHEN

Hi,all. Recently I am trying to use ANSYS ICEM to create the unstructured triangle grid. I write the grid data in CGNS format. The I found ICEM only gives the location information of the nodes and the nodes' numbers for every cell. I'm not sure if ICEM can give us further information, for example, the neighbours to the cells and the information about sides, just like a free software "EasyMesh". I'm a new comer in this field, so I really need the detailed books or some other kinds of references to ANSYS ICEM. Is there anyone who have some recommendations? Thanks in advance!
