Question

Frontal method is a _______ of Gaussian elimination method that uses the structure of finite element problem.

(a) Structure

(b) Variation

(c) Algorithm

(d) Data

I got this question during an interview.

My query is from Gaussian Elimination topic in section Matrix Algebra and Gaussian Elimination of Finite Element Method

Answer 1

Correct choice is (b) Variation

The best explanation: Frontal method is a variation of Gaussian elimination method that uses the structure of finite element problem. Elements can be stored in-core in a clique sequence as recently proposed by areas, this subset is called front and it is essentially the transition region between the part of the system already finished.
