cell neighbours

manuutin · August 17, 2010, 04:10

Hi! I need to get access to the neighboring cell numbers of of a given cell. In older star versions (3.*) this could be done with LQ(1:6,IP) that is in COMMON/DCO5/ , but I can't find equivalent in versions 4.*

. I only found a function that returns neighboring cells to a face: lfc(1:2,j).

Regards,
Mika

STAR4 is a face based code. Connectivity is via shared faces, not shared cell numbers. Also since STAR4 is a polyhedral code, a single array of 6,maxcel makes no sense any longer. It does not try to force every cell into a brick shape as did STAR3
