Question

To increase the order of accuracy, the multipoint method uses ___________

(a) highly stable two-level methods for prediction and correction

(b) higher-order two-level methods for prediction and correction

(c) additional points where data is already available

(d) additional points where data is interpolated

The question was posed to me in my homework.

Asked question is from Transient Flows in portion Transient Flows of Computational Fluid Dynamics

Answer 1

The correct answer is (c) additional points where data is already available

For explanation I would say: To increase the order of accuracy of the predictor-corrector method, multiple points are used instead of two points. The extra points are those obtained from the previous calculations.
