Dear SU2 users and developers,
I have just installed SU2 v3.2.0 on unbuntu. When I try to run parallel example, I found the SU2_PRT does nothing but only reading grid, twice. I think there should be a metis work during the grid partition, and several sub-grid files after the grid partition, but it does nothing and yields nothing. Why? Is there anything wrong with my installation? or other reason? Any answers will be appreciated. Here is the message.
Code:
$ mpirun -n 2 SU2_PRT inv_ONERAM6.cfg

Hello,

I had some problems with the MPI libraries that I solved: you can have a look at this post (http://www.cfd-online.com/Forums/su2...t-4-times.html) where I explained my problem (and the solution).
Maybe, You get the same problem...

I can't get an output either.

I looked at the src roughly. It sets size=1 at the beginning and all partition work is done within:

if (size > 1) {
all partition work
}

Sure, it will do nothing.

I think this 'size' means number of cpu cores as it is used at the end to print out finished on how many cores. So the if block may be changed to:

if (nZone > 1) {
all partition work. nZone is needed. Can do with one core or more cores.
}

But nZone=1 is also set at the begining.

I tried to set nZone=4 and/or add these lines in cfg file:

% --------------------------- PARTITIONING STRATEGY ---------------------------%
% Number of partitions of the domain
NUMBER_PART= 4

The program begin to "read grid file information" and then crashed.

Yeah, it is parallel installing problem. After carefully reinstall openmpi, the problem was solved!
Thanks, Laurent!
