This section is available for the Beam and Pipe Mechanics interfaces. All settings are analogous to the corresponding settings in the Spring section, but with forces replaced by moments and displacements replaced by rotations.

For Scalar (Same for all components) enter a single Loss factor for spring ηs, which is used to multiply all values of the spring matrix or spring force vector.
|
•
|
For Individual components select Isotropic, Diagonal, Symmetric, or Full, then enter values or expressions in the table for the Loss factor for spring ηk or ηf based on space dimension. The loss factors act on the corresponding components of the spring matrix or spring force vector. If you select Isotropic, the effect is the same as when you select Diagonal and enter the same value for all diagonal elements.

This section is available for the Beam and Pipe Mechanics interfaces. All settings in this section are analogous to the corresponding settings in the Viscous Damping section, but with forces replaced by moments and velocities replaced by angular velocities.

You can activate and deactivate Spring Foundation by assigning it to a constraint group. See Load Cases in the Structural Mechanics Modeling chapter.
