Hi, I ran into an error I have no idea how to adress. I'm trying to do a eularian-lagrangian analysis of particles in a pipe in crossflow. For this i decided to use DPMFoam, but it's not setup for Kepsilon and i've had to try and impliment it. However I'm getting this error I don't know how to deal with. Any help would be really appreciated.
I've treid to upload to folder without the mesh, If anyone has the time to have a look I'd really appreciate it. I'm running OpenFOAM 4.1 let me know if you need any more info Thank you Last edited by kinbean; July 11, 2017 at 07:43. |

Hi this is no longer a problem, I now am stuck with something else. The simulation runs then gives up after roughly the third timestep.
It didn't let me upload the full case folder. Nothing has changed in constants from last post. Does anyone have any ideas? Thank you for your help Here is the log.DPM file Code:

--------------------------------------------------------------------------
mpirun has exited due to process rank 4 with PID 3677 on
node MSI exiting improperly. There are two reasons this could occur:
1. this process did not call "init" before exiting, but others in
the job did. This can cause a job to hang indefinitely while it waits
for all processes to call "init". By rule, if one process calls "init",
then ALL processes must call "init" prior to termination.
2. this process called "init", but exited without calling "finalize".
By rule, all processes that call "init" MUST call "finalize" prior to
exiting or it will be considered an "abnormal termination"
This may have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).

Hi kinbean,
In your second post you say you fixed your issue with phi (which is the same problem that I am getting now). I couldnt figure our what you had changed to get it to work between your different attached files, could you possibly elaborate on how you fixed the phi issue. Regards, Robert |
