  Hi all.
  I simulate drilling and drill feed.
  Drill - rigid body. It has a deformable plate on it. Upon contact with the material - sandstone, all particles explode sharply and the calculation stops, why? Screenshots of settings and results:

  hi ,
  why are you repeating the cards?
  do you have any refernce to your work ?
  do you have any formal /guided training in LSDYNA in general ? and specific to paticel methods? , if not i suggest you first get the training started.
  how can you run 16 cores dispite the licenses you hold?
  cheers, Ram

    Yes, of course I passed all the basic courses on Ls-Dyna.
    I duplicated the material maps because:
    If the material map (snippet) is only in the geometry section, then the SECTION and PART maps do not see it, and the material is not written to the K file.
    I thought that if there are two places it will be useful both for Ls-Dyna WB and for recording with a K file.
    I have also attached an ARCHIVE.
    I put 16 cores, but in fact it works as much as the license allows.
