How long is the duration of the drilling? How many seconds? We simulated a screw  in wood that lasted 2.4 seconds. You can use the following strategies to speed up the calculation:

  • Increase the density of the rock.
  • Limit the SPG domain to only where you need it (see image below).
  • Use *CONTROL_MPP_DECOMPOSITION_ARRANGE_PARTS so distribute the SPG part to all processors.
  • Run the calculation on a cluster using MPP LS-DYNA with 32, 64, or more processors.


Let me know how it goes.
