Femap “How To” Video Series: Creating Constraint Equations

This is the first in a new series of “How To” videos that demonstrate some of the more advanced FEA modeling functionality accessible through Femap.

In this video we’ll see how to use Femap to set up a constraint equation that relates nodal degrees of freedom of a finite element model. Constraint equations can be used to create rigid connections between nodes, or calculate some useful quantity that is a function of nodal displacements.
