Hello,
I am teaching myself various numerical methods for integrating coupled, second order differential equations.
I am looking at Newmark-Beta methods
Sometimes I see Newmark Beta implemented as a predictor/corrector method.
Sometimes I see just Newmark methods alone.
And I get confused.
What IS the Newmark Beta method?
Is it so inextricably tied to the notion of predictor corrector that it is one and the same?
Or, are some of the sources just applying a "predictor/corrector" improvement on TOP of the Newmark scheme.
Here is a statement of Newmark (and I see no reference to predictor corrector)
https://en.wikipedia.org/wiki/Newmark-beta_method
Here is a statement of Newmark that launches right into prediction and correction
