Question

Which of these statements are wrong considering Control Volume based Finite Element Method?

(a) Control volumes are formed

(b) Integral form of the conservation equation is used

(c) The centroid of the elements is used

(d) Conservation equations are applied to the centroids

The question was asked in an interview for internship.

Question is from Numerical Methods topic in division Numerical Methods of Computational Fluid Dynamics

Answer 1

Correct choice is (d) Conservation equations are applied to the centroids

The explanation is: In CV-FEM, control volumes are formed by joining the centroids of the elements. The conservation equation in the integral form is applied to these control volumes as in the Finite Volume Method.
