Constraint & Constraint Equations

Constraint equations for the basis of the different constraint types in GSA:

  • Joints
  • Rigid constraints
  • Constraint equations
  • Tied interfaces

The form of a constraint equation is

us=∑aiup,iu_{s} = \sum_{}^{}{a_{i}u_{p,i}}

and is used to tie degrees of freedom in the model.
