Hi guys,

I am getting a strange error with Fluent 6.3 on parallel mode. Below is a summary.

> Case runs fine in serial.
> Runs fine in parallel with Standard scheme for pressure on node-A.
> Diverges when switched to PRESTO! on node-A,
> Runs fine with PRESTO! in serial or a different node.


I have reached the conclusion that there's some issue with the node.

But also baffled why the issue is invisible to Standard scheme but only affects PRESTO.

Can anyone tell me how the parallel implementation of the scheme differs??

Any help is appreciated.
