1.	If the pressure force is not treated as a surface force in the finite volume method, what will happen?(a) Non-conservative error(b) Stability issues(c) Boundedness problems(d) Convergence issuesI had been asked this question in an interview for internship.Enquiry is from Incompressible Flows in division Incompressible Flows & Compressible Flows of Computational Fluid Dynamics
Answer» Correct CHOICE is (a) Non-conservative error For explanation: Without USING the Gauss-Divergence theorem, the pressure FORCE can be treated as a volume integral itself. But, this will LEAD to a non-conservative form of EQUATIONS which, in turn, will result in non-conservative errors.
