LS-DYNA Specific Data Names

The following data names are only available for LS-DYNA, or have specific behavior for LS-DYNA.

distributedmass
This is the mass distributed from nodal rigid bodies to free nodes.
Type: double
engineeringmass
Corresponds to structuralmass + lumpedmass + nonstructuralmass.
Type: double
Exceptions:
For PART with PART_INERTIA:
Slave CRB of this part should have 0 mass.
The mass of the part should be equal to TM (if Iflag=1, transfer mass from slave to master).
For *CONSTRAINED_NODAL_RIGID_BODY_INERTIA
The mass of the slave nodes on the connected part should not be taken into account.
lumpedmass
The summed lumped mass added through *ELEMENT_MASS, *ELEMENT_MASS_NODE_SET, *ELEMENT_INERTIA or *ELEMENT_SEATBELT_ACCELEROMETER.
Type: double
nonstructuralmass
The summed nonstructural mass added through *ELEMENT_MASS_PART_SET, *ELEMENT_MASS_PART or NSM in *SECTION.
Type: double
rigidbodymass
Mass in nodal rigid bodies. This is the mass transferred from deformable nodes to nodal rigid bodies. This includes the mass transfer of the lumped mass defined on deformable elements of the nodal rigid body.
Type: double
solvertpartmass
For rigid parts:
  • Structural mass + lumped mass + non-structural mass + mass transferred from deformable nodes (including lumped mass ; NSM applied on these nodes) + mass transferred from other rigid parts (merged)
  • If PART_INERTIA is defined then the mass/COG/inertia are equal to the ones specified (if Iflag=1 in xtranodes or crb these are added too)
For deformable parts:
  • Structural mass + non-structural mass – mass in nodal rigid bodies (lumped mass excluded)
Type: double
structuralmass
The summed structural mass of the elements in the component.
For PART_INTERIA, reports the translational mass (TM) value.
Type: double
totalmass
Corresponds to distributedmass + lumpedmass + nonstructuralmass + rigidbodymass + structuralmass + transferredmass
Type: double
transferredmass
This is the mass transferred from deformable nodes to rigid materials. This includes lumped mass transfer from rigid or deformable nodes to the rigid materials.
For rigid material this is the mass gained from deformable (+). For deformable parts this is the mass lost to rigid material (-).
Type: double
