Exc 15: Error running base simulation with updated policy
ChristianZaeh opened this issue · comments
I followed the last steps of the exercise 15 and get the following error when running the ./Allrun and ./Allrun.pre files:
./Allrun.pre Running blockMesh on /home/christian/drlfoam/examples/base_sim/base Running setExprBoundaryFields on /home/christian/drlfoam/examples/base_sim/base Running decomposePar on /home/christian/drlfoam/examples/base_sim/base Error getting 'numberOfSubdomains' from 'system/decomposeParDict' Running renumberMesh (1 processes) on /home/christian/drlfoam/examples/base_sim/base Error getting 'numberOfSubdomains' from 'system/decomposeParDict' Running pimpleFoam (1 processes) on /home/christian/drlfoam/examples/base_sim/base
Thank you for the help :)
Hi @ChristianZaeh,
since the command numberOfSubdomains is not found, maybe you forgot to source the setup-env. Provided that the base directory is still located in drlfoam/examples/test_training/base you can try the following steps after making a copy of the original base folder:
- from the top-level of the repository, execute the command
source setup-env - cd into the
drlfoam/examples/test_training/basefolder - execute
./Allclean - execute
./Allrun.pre
You can add the parameter --container to the first point as source setup-env --container if you don't have a native openfoam installation. In this case you first have to build the singularity container at the top level of the drlfoam directory as described in the drlfoam repository. Please let me know if this doesn't fix the issue.

Hi @JanisGeise
ok, I thought the copy has to stay in the drlfoam folder. I moved it now to the exercise folder and setup the environment. I now get:
./Allrun.pre: line 3: DRL_BASE: parameter null or not set
Thank you and kind regards
Christian
yes, the base directory has to stay in the same directory (drlfoam/examples/test_training/). The copy is just for backup, in case you want to check out the settings or try out another policy. It is also important that the name of the directory remains base and the name of the policy used policy.pt.

okay I set up the from the top level folder and following the steps I still get:
./Allrun.pre Running blockMesh on /home/christian/drlfoam/examples/test_training/base Running setExprBoundaryFields on /home/christian/drlfoam/examples/test_training/base Running decomposePar on /home/christian/drlfoam/examples/test_training/base Error getting 'numberOfSubdomains' from 'system/decomposeParDict' Running renumberMesh (1 processes) on /home/christian/drlfoam/examples/test_training/base Error getting 'numberOfSubdomains' from 'system/decomposeParDict' Running pimpleFoam (1 processes) on /home/christian/drlfoam/examples/test_training/base
Regards Christian
ok, can you check out the log.decomposePar file if there are any error messages?
Regards,
Janis
yes, there is:
/home/christian/drlfoam/openfoam/RunFunctions: line 210: decomposePar: command not found

@ChristianZaeh , unfortunately I can't reproduce the error. Can you describe what you have done (e.g. what commands did you execute) exactly after the training finished? Further, did you encountered any problems when running the training?
@AndreWeiner, I noticed that I forgot to mention in issue #30 that the parameter timeStart in system/controlDict need to be set to zero for the coefficients as well as for the probes in order to write out the data during the simulation.

Hi @ChristianZaeh,
is this issue resolved from your point of view?
Best, Andre
Hi @AndreWeiner,
Sorry for the late response. I did not get it to work, but I haven't tried it any further due to exams.
Best,
Christian
Alright, thanks for the quick response. Feel free to bring your laptop to the meeting before the exam or to schedule a separate appointment to look at your setup together.
I'll close this issue for now.
Best, Andre
