Changes in the position of the structural system are displayed on nodes, lines, members, surfaces, and solids of the model; select the respective subcategory in the tables:
- "Results by Node"
- "Results by Line"
- "Results by Member"
- "Results by Surface"
- "Results by Solid"
Grouping of Results
The results of eigenvalue analyses—that is, the results of linear stability analyses—are grouped by the basic objects of the model and the mode shape; select the relevant tab (spreadsheet) in the tables:
- Node / Line / Member / Surface / Solid No., or
- Mode Shape No.

Coordinates of Result Points
- Results on surfaces and solids are based on the grid points of the objects and—just like nodal results—refer to the global coordinate system. For more information, refer to the RFEM manual.
- Results on members and lines are displayed at special points ("Location x") along the objects in the local coordinate system.
- When selecting a grid point or a "location x" in the tables, the corresponding position is marked in the model.
Standardized and Absolute Results
Displacements and rotations from eigenvalue analyses—that is, from linear stability analyses —are displayed as dimensionless numerical values. For the standardization / scaling the results to the reference length "1", one of the following bases is used:
| |u|= 1 | maximum total displacement |u|= (uX2 + uY2 + uZ2)0.5 |
| max {uX; uY; uZ} = 1 | maximum translational component of the mode shape vector; only displacements are taken into account |
| max {uX; uY; uZ; φX; φY; φZ} = 1 | maximum translational or rotational component of the mode shape vector; displacements and rotations are taken into account |
| {uj}T [KG] {uj} = 1 | maximum deformation value from the geometric stiffness matrix |
You can set the basis of the standardization in the Results navigator under "Scaling of Mode Shapes".

Displacements and rotations from nonlinear, incremental calculations are displayed in absolute numerical values.
