creates a GENEL card
The required input is the {UL} list and the lower triangular portion of [K] or [Z]. Additional input may include the {UD} list and [S]. If [S] is input, must also be input. If {UD} is input but [S] is omitted, [S] is internally calculated. In this case, {UD} must contain six and only six degrees-of freedom.
- _properties = ['node_ids', 'ul_nodes', 'ud_nodes', 'nodes']

- property node_ids
- property nodes
- safe_cross_reference(model: BDF, xref_errors)[source]
Cross links the card so referenced cards can be extracted directly
- Parameters:
- modelBDF()

gets the {UD} nodes
- property ul_nodes
gets the {UL} nodes
- class pyNastran.bdf.cards.elements.elements.PLOTEL(eid, nodes, comment='')[source]
Bases:
BaseCard
Defines a 1D dummy element used for plotting.
This element is not used in the model during any of the solution phases of a problem. It is used to simplify plotting of structures with large numbers of colinear grid points, where the plotting of each grid point along with the elements connecting them would result in a confusing plot.
