elements

The following data names are only available for "core" solver templates routinely maintained by Altair:

cogx: The x center-of-gravity for the element. This takes into account the thickness and mass of the element.
cogy: The y center-of-gravity for the element. This takes into account the thickness and mass of the element.
cogz: The z center-of-gravity for the element. This takes into account the thickness and mass of the element.
IXX: The I_xx component of the mass moment of inertia for the element. This is calculated about the global origin (0,0,0).
IXXcog: The I_xx component of the mass moment of inertia for the element. This is calculated about the element COG.
IYY: The I_yy component of the mass moment of inertia for the element. This is calculated about the global origin (0,0,0).
IYYcog: The I_yy component of the mass moment of inertia for the element. This is calculated about the element COG.
IZZ: The I_zz component of the mass moment of inertia for the element. This is calculated about the global origin (0,0,0).
IZZcog: The I_zz component of the mass moment of inertia for the element. This is calculated about the element COG.
IXY: The I_xy component of the mass moment of inertia for the element. This is calculated about the global origin (0,0,0).
IXYcog: The I_xy component of the mass moment of inertia for the element. This is calculated about the element COG.
IXZ: The I_xz component of the mass moment of inertia for the element. This is calculated about the global origin (0,0,0).
IXZcog: The I_xz component of the mass moment of inertia for the element. This is calculated about the element COG.
IYZ: The I_yz component of the mass moment of inertia for the element. This is calculated about the global origin (0,0,0).
IYZcog: The I_yz component of the mass moment of inertia for the element. This is calculated about the element COG.
mass: The summed total mass of the element. This takes into account both structural and nonstructural mass.
nonstructuralmass: The summed nonstructural mass of the element.
principalaxis1: The x, y and z components of the first principal axis for the element. This is calculated about the global origin (0,0,0).
principalaxis1cog: The x, y and z components of the first principal axis for the element. This is calculated about the component COG.
principalaxis2: The x, y and z components of the second principal axis for the element. This is calculated about the global origin (0,0,0).
principalaxis2cog: The x, y and z components of the second principal axis for the element. This is calculated about the component COG.
principalaxis3: The x, y and z components of the third principal axis for the element. This is calculated about the global origin (0,0,0).
principalaxis3cog: The x, y and z components of the third principal axis for the element. This is calculated about the component COG.
structuralmass: The summed structural mass of the element.
thickness: The thickness of the element. This only takes into account the thickness of the property assigned to the element.

The following data names have specific behavior for LS-DYNA, as indicated below:

nonstructuralmass: The summed nonstructural mass added through *ELEMENT_MASS_PART_SET, *ELEMENT_MASS_PART or NSM in *SECTION.
structuralmass: The summed structural mass of the elements in the component.; For PART_INTERIA, reports the translational mass (TM) value.
