Notes

PBAR

Defines the properties of a simple beam (bar), which is used to create bar elements via the CBAR entry.

PBARL

Defines the properties of a simple beam (bar) by cross-sectional dimensions, which is used to create bar elements via the CBAR entry.

Exported in large field format by optistructlf template.

PBEAM

Defines the properties of a beam that is used to create beam elements via the CBEAM entry.

Exported in large field format by optistructlf template.

PBEAML

Defines the properties of a beam element by cross-sectional dimensions that are used to create beam elements via the CBEAM entry.

Exported in large field format by optistructlf template.

PBUSH

Defines the nominal property values for a generalized spring.

PDAMP

Specifies the damping of a scalar damper element using defined CDAMP1 entry.

PELAS

Used to define the stiffness and stress coefficient of a scalar elastic element (spring) by means of the CELAS1 entry.

PGAP

Defines properties of the gap (CGAP) elements.

PMASS

Defines the mass value of a scalar mass element (CMASS1 or CMASS3).

PROD

Defines the properties of a rod, which is referenced by the CROD entry.

Exported in large field format by optistructlf template.

PVISC

Defines properties of a one-dimensional viscous damping element (CVISC entry).

PWELD

Defines properties of connector (CWELD) elements.

HM_ELAS

Defines properties for a HM_Spring element, as explained in Using HM_ELAS.

Notes:

Only one property definition is allowed on each property collector. So for definitions like PMASS, which allow more than one property definition on the same card, this is separated on import into four different cards.

1-D elements can be organized into components with 2-D and 3-D elements and these component groupings are maintained on export and import. However, this usage is not recommended.

To assign 1-D elements to property collectors, select the property collector from property = in the appropriate 1D element panel.
