Greetings to all!

@samiam1000: The first line shouldn't have quotes:

Code:

#!/bin/bash

There is a major flaw in your current script: "foamJob -p" will launch and run in the background automatically, leading the rest of the script to executed immediately after foamJob is executed. A quick fix would be to run with "foamJob -s -p".

By what I can understand, it's not foamJob that needs nohup, it's the call to this script that needs this! For example, if you call this script "runcase.sh", you'll need to:

The script should be something like this:

Code:

#!/bin/bash foamJob -s -p buoyantPimpleFoam reconstructPar cd ../1DegNew/ mapFields -consistent ../1DegStartNew -sourceTime 100 decomposePar buoyantPimpleDyMFoam_MS sed -i 's/1/2/' system/controlDict buoyantPimpleDyMFoam_MS sed -i 's/2/3/' system/controlDict buoyantPimpleDyMFoam_MS sed -i 's/3/4/' system/controlDict buoyantPimpleDyMFoam_MS sed -i 's/4/5/' system/controlDict buoyantPimpleDyMFoam_MS sed -i 's/5/6/' system/controlDict
After you edit and save the script for the first time, make sure it is an executable script:

Code:

chmod a+x runcase.sh
Then for running the script:

Code:

nohup ./runcase.sh

Last but not least, why aren't you following the examples shown in the tutorials? For example, see "incompressible/simpleFoam/turbineSiting/Allrun". The downside of this example is that it will only run in the machine where it is launched...

Best regards,
Bruno

Code:

'#!/bin/bash'



nohup foamJob -p buoyantPimpleFoam;



reconstructPar;



cd ../1DegNew/;



mapFields -consistent ../1DegStartNew -sourceTime 100;



decomposePar;



buoyantPimpleDyMFoam_MS;



sed -i 's/1/2/' system/controlDict;



buoyantPimpleDyMFoam_MS;



sed -i 's/2/3/' system/controlDict;



buoyantPimpleDyMFoam_MS;



sed -i 's/3/4/' system/controlDict;



buoyantPimpleDyMFoam_MS;



sed -i 's/4/5/' system/controlDict;



buoyantPimpleDyMFoam_MS;



sed -i 's/5/6/' system/controlDict;

Is that correct?

Thanks a lot,

No. I was answering the mpirun-issue. I don't use foamJob so I can't comment on your script
