    the syntax in command line for the submission is -nt 4 this may be the cause? you have -nthread4 with no space, -both is redundant here since -both is default

    Thanks, it worked. But now I'm getting "initial penetration error". Can you please help me with that?

    I'm attaching the file.

    You have several areas in your mesh where the tubes are not correctly merged in the mesh (unequivalenced edges) such as below, that was causing a 0 gap condition in your contact (not allowed in type 7) I fixed in the attached and also reduced your gapmin to 0.75. I attached my version, it runs, but you should do your own checks and fixes (edges panel in HW)

    Letting the previous one run, I noticed you hadn't added anything to the rwall, so it just passes through, I added the 1st 50mm in here and moved the wall closer too, to get the structure in contact with it more quickly
