NASTRAN Types;

 

CBEAM 

Beam Element Connection

Defines a beam element.

 

CBAR

Simple Beam Element Connection

Defines a simple beam element.

 

RBAR

Rigid Bar

Defines a rigid bar with six degrees-of-freedom at each end.

 

RBE2

Rigid Body Element, Form 2

Defines a rigid body with independent degrees-of-freedom that are specified at a single grid point and with dependent degrees-of-freedom that are specified at an arbitrary number of grid points.

 

CBUSH

Generalized Spring-and-Damper Connection

Defines a generalized spring-and-damper structural element that may be nonlinear or frequency dependent.

 

CBUSH1D

Rod Type Spring-and-Damper Connection

Defines the connectivity of a one-dimensional spring and viscous damper element.

 

CELAS1

Scalar Spring Connection

Defines a scalar spring element.

 

CELAS2

Scalar Spring Property and Connection

Defines a scalar spring element without reference to a property entry.

 

CJOINT

Kinematic Joint Connection (SOL 402)

Defines a kinematic joint connection

 

RBE3

Interpolation Constraint Element

Defines the motion at a reference grid point as the weighted average of the motions at a set of other grid points.

 

RSPLINE

Interpolation Constraint Element

Defines multipoint constraints for the interpolation of displacements at grid points.

 

FOU3

Coupling Element Connection

Connects a grid point with six DOF to a grid point used in the connectivity of a Fourier axisymmetric element for SOLs 402 and 414.
