Description
Defines a spring boundary condition to be used for mechanical analyses using the Elmer solver.
introduced in version 0.21: The spring constraint can be used for the equations Deformation and Elasticity.
Usage
- Either use the toolbar button Spring or the menu Model → Mechanical boundary conditions and loads → Spring.
- In the 3D view select the faces to which the spring should be applied.
- Specify the normal or tangential stiffness (in N/m) and select which one Elmer should use.
