Question

In Finite Element Method (FEM), which option is not correct with respect to discretization or mesh generation?

(a) Density of elements depends on the degree of accuracy desired

(b) Choice of element type may depend on the geometry of domain

(c) For better accuracy correct formulae has to be applied

(d) Some general rules govern mesh generation

This question was addressed to me in exam.

I'm obligated to ask this question of Some Comments on Mesh Generation and Imposition of Boundary Conditions in chapter Single Variable Problems of Finite Element Method

Answer 1

Right option is (c) For better accuracy correct formulae has to be applied

For explanation I would say: In Finite Element Method (FEM), for discretization purpose there are no specific formulae to obtain mesh generation as it depends on the expertise of the analyst. However, the density of elements,choice of element type may depend on the degree of accuracy desired and the geometry of domain.
