Question

In Finite Element Method (FEM), In order to increase accuracy of a solution, while domain discretization, more than one node is to be placed at a point source.

(a) True

(b) False

The question was posed to me during an online exam.

This key question is from Some Comments on Mesh Generation and Imposition of Boundary Conditions topic in chapter Single Variable Problems of Finite Element Method

Answer 1

The correct answer is (b) False

Easiest explanation: While domain discretization, a single node is placed at a point source and the point source is assumed to lumped at that node. Since there is no division of a point load, its discretization plays no role in determining accuracy of the solution.
