Restype Nodal data type:
Nodal time step
Mass variation (see time step control /DT/Eltyp/Iflag). 1
Output of added inertia per nodes. 2
Non-diagonal mass variation (see time step control /DT/AMS). 3
Damage for TYPE2 interface. 4
Nodal density. 6
Nodal pressure. 6
Nodal temperature. 5 6
Nodal sound speed.
This output is only available for FVMBAG1.
Nodal volumetric fraction, used with LAW37 and LAW51.


  1. DMAS = DM M 0 with D M = M M 0 .
    M 0
    Nodal mass at the beginning of the restart
    Current mass
  2. D M is re-set to 0 at the beginning of each restart file.(1)
    D I N E R = ( I n e r t i a ( t ) l 0 l 0 )
    l 0
    Nodal inertia at the beginning of the current run
    I n e r t i a ( t )
    Current inertia
  3. In case /DT/AMS is used, a non-diagonal mass matrix is used, which allows to increase the time step on each line of the mass matrix, the lumped mass M M 0 is increased with some value Δ M which is compensated with non-diagonal terms, in order for the total mass to remain constant. Then: (2)
    N D M A S = ( Δ M M 0 )
  4. DAMA2 damage percentages for /INTER/TYPE2 with rupture (Spotflag = 20, 21, or 22):(3)

    min ( 100 , 100 tangent r e l a t i v e d i s p l a c e m e n t max t a n g e n t r e l a t i v e d i s p l a c e m e n t )
  5. /ANIM/NODA/TEMP is used generally to output nodal temperature for finite element formulation of thermal exchange.
  6. These options are also available for 3D ALE and FVM airbag problems. The material density, pressure, and temperature is extrapolated to the element nodes, in this case. For FVM airbags the values are extrapolated only to nodes of external and internal airbag surfaces.
