Batch command for coupled simulations

Hello,
I have a simulation that need an external exe to run.
On my local machine i use the Coupling Server option from the GUI to do it.
But now i would like to run my simulations on a cluster. I know the batch command to run a simulation without an exe, but how can i say to EDEM to use the exe (or so) to run the simulations.
Best regards,
GUDENDORFF Gauthier

Hi Gauthier,
We have different ways of doing this, the EDEM batch commands are detailed in this blog:
How to use EDEM Batch Commands
To start EDEM 'listening' for a coupling you need to include the --cs flag:
edem -c -i mysim.dem --cs
Then if you run another program/.exe/.so on the same server that couples to EDEM it will connect.
A few points to note is that you need to run EDEM first to start it listening and it's best to give it a few seconds to open the file and start listening. Typically I put in a ~10 s wait after the EDEM command before running another however if you are loading a large deck with particles that would need longer to open.
This means you need to launch 3 commands, something like:
start cmd /k edem -c -i mysim.dem --cs
timeout /t 10 /nobreak
my.exe
This is a windows version that starts EDEM running in a separate command window, this is so you can then go to the next line which is a 10 s wait, then launching your .exe.

Il will try it soon, but no reason to not work!
