Dear foamers.

There is 2 nodes and each node has n processors.

The default ver is 2.4 and I wanted to dev-version.

When I use single node. I just typed ‘ofdev’ to change the version.

Whenever I change node, I have to type the command ‘ofdev’.

Now I’m trying to run my case with multiple nodes in a cluster which has several versions of OpenFOAM.

So, I command as below.

mpirun —hostfile machines -np 12 Solver(ex: InterFoam) > log &

I have machines file to fefine node and process as below

node1 cpu=6
node2 cpu=6

And the first line of the log file is

bash: of240: command not found

And just the node I’m in works.

I think it because the default ver is 2.4 and there was no change command for other node in my command for running openfoam with multiple nodes.

How can I fix this problem?

I refered BPS script from https://www.hpc.dtu.dk/?page_id=1024#Parallel

There is a command as

# -- load OpenFOAM --
module load OpenFoam/2.3.0/gcc-4.8.3-openmpi

I could load openmpi with

module mpi/openmpi-x86_64

and then ompi201gsh and mpi/openmpi-x86_64 are listed when I type module list command.

But I have no idea how to load specific version of openfoam with module command.

Would someone give me a hint?

Thank you in advance.


—————————————
I knew I had to change my bashrc

I edit home/users/dokeun/.bashrc
I add the code

export FOAM_INST_DIR=/usr/local/OpenFOAM; . $FOAM_INST_DIR/OpenFOAM-dev/etc/bashrc

in the end of the file.
But the log is as below

————————————————————————————————————-
mpirun was unable to find the specified excutable file, and therefor did not launc the job. This error was first reported for process rank 0; it may have occurred for other processes as well.
NOTE: A common cause for this error is misspelling a mpirun command line paramter option (remember that mpirun interprets the first unrecognized command line token as the excutable).

Node:          Dnode1
Excutable: multiphaseInterFoam

What i ran is

#PBS -l nodes=2:ppn=12
