In the formulation of governing equations, which option does not signify the characteristics of a weight function? Correct Answer Weight function must denote a non-dimensional quantity
In the development of the weak form, we consider a typical element and multiply its governing equations with weight functions. They can be interpreted physically for a given equation; for example, in the momentum equation, the weight function must be interpreted as velocity. For the representing volume change, weight function is like pressure. Thus, it can be a dimensional quantity.
