In velocity-pressure formulation in FEM, which step is not used in the development of a weak form?

(a) Multiply governing equations with weight functions

(b) Integrating over the element domain

(c) Integrating by parts

(d) Performing coordinate transformation

This question was posed to me by my school teacher while I was bunking the class.

Enquiry is from Velocity topic in section Flows of Viscous Incompressible Fluids of Finite Element Method

The correct answer is (d) Performing coordinate transformation

Explanation: In the development of weak form, we consider a typical element and develop the finite element model over it by following the three-step procedure. Firstly, multiply governing equations with weight functions and Integrate over the element domain. Secondly, perform integration by parts and, thirdly, define the coefficient of weight function.
