[OpenFOAM.com] OpenFoam data lost after reboot

cfd90 · October 6, 2021, 13:35

Hello,

I installed OpenFoam via Docker on my Mac (Big Sur) and I was able to run the tutorial cases and even create my cases (4 or 5 of them), each in a different folder in the /home/openfoam/run/ directory.

I rebooted my computer yesterday and I cannot find any of my data since then, it's all gone. I tried to see if maybe it had something to do with Docker but I couldn't find the right answer. The only help I could find was on this website but even then it didn't answer my question (https://www.cfdengine.com/blog/how-t...e-with-docker/).

Could someone help me figure out if I'm doing something wrong or if all my data is just gone for good?

Thank you for your help,
Sam

The data are not saved within docker, but on the host filesystem. Eg, you start openfoam-docker from some "/somepath/somewhere", this is mounted as "/home/openfoam" within your docker instance. So what you created as "/home/openfoam/run" in the container should have been saved as "/somepath/somewhere/run" on your machine.
Of course you'll have to remember where that "/somepath/somewhere" actually was.
