Mass Scaling for Minimum Time Step Size

 401

Adjusting density to user defined time step size

402

Two alternatives

  • Have the same time step size for all elements by adjusting density. DT2MS on *CONTROL_TIMESTEP positive (Control Card 9, Columns 41-50)
  • Mass scaling applies only to elements with 403DT2MS on *CONTROL_TIMESTEP negative (Control Card 9, Columns 41-50)
