RBE3
Defines the motion at a reference grid point as the weighted average of the motions at a set of other grid points.

Fields
| Field | Contents |
|---|---|
| EID | Element identification number. (Integer > 0) |
| REFGRID | Reference grid point identification number. (Integer > 0) |
| REFC | Component numbers at the reference grid point. (Any of the integers 1 through 6 with no embedded blanks.) |
| WT1 | Relative weighting factor for components of motion on the following entry at grid points G1,j. This value does not affect the solution because the user is limited to a single relative weighting factor. (Real) |
| C1 | Component numbers with weighting factor WT1 at grid points G1,j. (Any of the integers 1 through 6 with no embedded blanks.) |
| G1,j | Grid points with components C1 that have weighting factor WT1 in the averaging equations. (Integer > 0) |
Remarks
- It is recommended that for most applications only the translation components 123 be used for C1. An exception is the case where the G1,j are colinear. A rotation component may then be added to stabilize its associated rigid body mode for the element.
