CFDEM coupling case runs but results delete themselves before I can view! Please help!

Submitted by nasser225 on Sun, 10/09/2016 - 09:07

I have successfully installed Liggghts, cfdem and openfoam. Liggghts is perfectly running, went on to test cfdem coupling and I can execute the 'Allrun.sh' files in tutorial folders but no matter which I pick, CFDEM seems to be deleting the results files before I can have a look at them!

I check the case folder and I can see the cfdem dumps being created '0, 0.1, 0.2 etc' but when the run is complete, these are deleted....

Here is snippet of the terminal window at the end of the run:

Hello Nasser,
the files are deleted automatically for avoiding the generation of large amounts of data on your harddrive within the course of the test run. There are two ways to keep the data: you can either type "Ctrl+C" at the end of a test run instead of hitting enter (after closing the graphs, when the line "deleting data at: [some path]" is shown. Another possibility would be to comment the lines in the *.sh file (parCFDEM.sh, code section at the bottom of the file).
Best regards,
Alice
