assemblies

Unless otherwise specified, data names are accessible in level 3 only.

activesuppressed: Returns non-zero if the entity is set inactive, 0 otherwise. Type: integer
assemblies: The list of sub-assemblies in an assembly. Type: entity array; For access via the template, this is a pointer to the sub-assemblies within an assembly (pointer value is the sub-assembly ID).
assembly: Pointer to the assembly (use with the pointer - pointer1.assembly.name).

color: The color of the entity. Type: integer
component: Pointer to the component (use with the pointer - pointer1.component.name).
components: The list of components in an assembly. Type: entity array; For access via the template, this is a pointer to the components within an assembly (pointervalue is the component ID).
definedentity: True if the entity is defined, false otherwise. Type: Boolean
id: The ID of the entity. Type: entity
include: The ID of the include file the entity is organized in. Type: entity
includeid: The ID of the include file the entity is organized in. Type: unsigned int.
internalid: The ID of the entity. Type: unsigned int.
mass: The summed total mass. This takes into account both structural and nonstructural mass.
multibodies: The list of multibodies in an assembly. Type: entity array; For access via the template, this is a pointer to the multibodies within an assembly (pointervalue is the multibody ID).
multibody: Pointer to the multibody (use with the pointer - pointer1.multibody.name).
name: The name of the entity. Type: string
nonstructuralmass: The summed non-structural mass.; Type: double
numberofassemblies: The number of sub-assemblies in an assembly. Type: integer
numberofcomponents: The number of components in an assembly. Type: integer
numberofmultibodies: The number of multibodies in an assembly. Type: integer
outputsuppressed: Returns non-zero if the entity is set "do not export", 0 otherwise. Type: integer
structuralmass: The summed structural mass.; Type: double

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

totalmass: Corresponds to distributedmass + lumpedmass + rigidbodymass + structuralmass; Type: double
