We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

The difference between the stiffness matrix at different harmonic indices is the constraint equations created to enforce the harmonic index shape.  These constraint equations are created during solution.  A possible way to create a model for a harmonic index greater than 0 is to issue the command cycopt,hindex,N in a commands object.  Then the system matrices will be only for harmonic index N.
