Question

In sequential methods for solving coupled equations, except the variable for which the equations are solved, the other variables are treated as ___________

(a) zeros

(b) unknowns

(c) known values

(d) ones

The question was posed to me in quiz.

Asked question is from Numerical Methods topic in section Numerical Methods of Computational Fluid Dynamics

Answer 1

The correct answer is (c) known values

To elaborate: In sequential methods of solving coupled equations, the variable for which the system is solved is treated as unknown. All other variables are treated as known values with some approximations.
