Question

Element connectivity is responsible for ___________

(a) consistency of the fluxes of different elements

(b) consistency of the equations formed for different elements

(c) flow field variables

(d) gradient of the flow field variables

The question was asked in an interview for job.

The origin of the question is Numerical Methods in portion Numerical Methods of Computational Fluid Dynamics

Answer 1

The correct answer is:

(b) consistency of the equations formed for different elements

Element connectivity is responsible for ensuring that the equations formed for different elements in the numerical grid are consistent with each other. It refers to the relationship between neighboring elements (or cells) in the computational mesh. This connectivity ensures that fluxes, boundary conditions, and other variables are correctly transferred and aligned between adjacent elements, maintaining the accuracy and consistency of the numerical solution across the entire domain.
