Issue with Selective Mass Scaling

  Hello All,
  
  I am trying to perform a dyanmic crash simulation in LSDYNA.
  
  In the FE Model I have a part with two mesh sizes,
  Size 1: with 3mm + 1mm(at thin areas) and Size 2: with 1mm mesh. Both are tetra meshed.
  
  With my current timestep of E-4 the part was having huge mass addition that is why I decided to add the part in the SMS set but when I try to run the simulation,
  with Size 1: I get out-of-range forces at a location which is far from the part in question.
  and with Size 2: the simulation does not run at all. It's stuck before calculation go to the transient phase.
  
  Did anyone face similar issues? Any suggestions are greatly appreciated.
  
  Thank You.
