Hey all,

I was going through a few video lectures on youtube. To be specific, this is the video I watched.

Now, the professor in the video talks about Dynamic reduction techniques and puts Guyan reduction in that category. For a fact, Guyan reduction is also called Static condensation and when I come to think of 'Static' condensation as a 'Dynamic' reduction technique I am confused.

The term dynamic stands for something that varies linearly with time. Somwehow I can't correlate this with Static Condensation where we ignore the inertial (mass) terms and assume static equilibrium between the master nodes and slave nodes while solving this equation: [K]{u} = {F}.

Could anyone please explain this?

Thanks.
