     Massless nodes

     The following massless nodes were found

       75208       75209

 *** Warning 30131 (INI+131)

     total number of massless nodes = 8

 The LS-DYNA time step size should not exceed     8.115E-05

 to avoid contact instabilities.  If the step size is

 bigger then scale the penalty of the offending surface.
