Hi,
I am examining the SU2 partitioned mesh file and I had a couple of questions. I'll refer to the vertex as a "node". E.g. portion of the file on partition 1 --- for a 2 process run: MARKER_TAG = SEND_RECEIVE MARKER_ELEMS 95 SEND_TO = 2 1 23 0 1 215 0 .. .. Can I assume that there are 95 Nodes in this partition sending to process 2 and that the second column are the local node indices of the send nodes ? I also see that, following this block of data, there is a SEND_TO = -2. What does the -2 indicate ? -- receive from process 2 ? Also referring to the above block of data, if node 23 in process 1 sends to process 2, the corresponding receiver node in process 2 should be the first node in the array to receive the data ? ( looking at the file in partition 2?) Thank you, Dominic |

You are right, a positive value in SEND_TO means send to, and a negative means receive from. And as you point out, the lists of nodes are sorted. Your example is perfect. Thanks for using SU2, Best Francisco |
