## 11.4. CEL Access of the Rigid Body State Variables

The rigid body state variables hold the position, orientation, and the first and second derivatives of position and orientation, of a rigid body object or an immersed solid domain that is governed by a rigid body solution. The rigid body state variables can be accessed through CEL in CFX-Pre and CFX-Solver Manager (but not in CFD-Post) via the `rbstate` function. For details on the `rbstate` function, see Quantitative Function List in the CFX Reference Guide.
