Default Help with parallel UDFs needed

Hello,

I tried to write an UDF for a parellel calculation.

In that UDF is a loop over all cells and some cell values are written in an array (cell volume and fraction of second phase). My computer is fitted with two cores, so i started two node processes. The loop is working on all cells, as far as I see, and it accesses the data on node 0 and node 1, like expected.

After runnig over all cells the array is sent from nodes to host, using the FLUENT-macro 'node_to_host_real'.

The host receives only the part of data from node 0, the node 1 data is not passed to host. Looking in the manual, I found no hint about restictions of 'node_to_host'. Also, I found nothing about any special treatment of node 1.

How I can send data from all nodes (read: all cells in parrallel calculations) to the host? Any hints are wellcome,

N.
