Question

Element connectivities are used for _____

(a) Traction force

(b) Assembling

(c) Stiffness matrix

(d) Virtual work

The question was posed to me in a national level competition.

This key question is from One Dimensional Problems topic in section One Dimensional Problems of Finite Element Method

Answer 1

The correct answer is (b) Assembling

To explain: Element connectivity means “Assemble the element equations. To find the global equation system for the whole solution region we must assemble all the element equations. In other words we must combine local element equations for all the elements used for discretization.
