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

  1. Either use the toolbar button Spring or the menu Model → Mechanical boundary conditions and loads → Spring.
  2. In the 3D view select the faces to which the spring should be applied.
  3. Specify the normal or tangential stiffness (in N/m) and select which one Elmer should use.
