Restart CFX simulation in batch mode using ccl

Hi everyone,
I am running RANS-simulations in CFX 2020R2. I did the setup of the simulation in CFX-Pre and created a .def-file from that: (RANS.def) which I then moved to the storage space on the cluster where I am working. I use an .sh-script file (runCFX_1.sh) to execute the simulation in batch mode on the cluster. Since my settings in CFX-Pre for the convergence criteria (RMS with 1E-4) and the max. iterations of 1000 lead to unsatisfying results, I would like to restart the simulation from the latest iteration which is 1000 and go further up to 2000 iterations. During the first run, the files "RANS_001.res", "RANS_001.out" and the folder "RANS_001/" containing the files "900_full.bak", "reread" and "trn" were created. I've read in some forums that you can use "-inject-commands" in the .sh-script in order to change parts of the settings in the batch mode. Therefore, I adjusted my runCFX_1.sh script and I created the file "newccl" that includes the code for setting the max. iterations up to 2000 and alterning the convergence criteria. Apart from that, I want to activate "double precision" from now on and so I used the command "-double" with the "cfx5solve"-command in my .sh-script. When I execute the script, it seems to run properly but when I have a look into the newly created "RANS_002.out"-file I can see that double precision is activated while the settings to be changed using the "-inject-commands" function remain unaltered. What do the files "runCFX_1.sh" and "newccl" have to look like to make it work? Thanks for your help! Here you find the codes: runCFX_1.sh Quote:
