Question

The independent variables in Eulerian approach are __________ and __________

(a) instantaneous time and instantaneous position

(b) initial time and instantaneous position

(c) instantaneous time and Initial position

(d) initial time and initial position

This question was posed to me in quiz.

The origin of the question is Governing Equations topic in section Governing Equations of Fluid Dynamics of Computational Fluid Dynamics

Answer 1

The correct option is (a) instantaneous time and instantaneous position

The best explanation: Current position and time are the variables on which other variables depend on in Eulerian approach. These are the independent variables.
