Equation discretization is the process of converting ___________ PDEs into discretized equations.(a) Open-form(b) Closed-form(c) Linear(d) Quasi-linearThe question was asked in an internship interview.My doubt is from Discretization in portion Basic Aspects of Discretization, Grid Generation with Appropriate Transformation of Computational Fluid Dynamics

Answer»

Right answer is (b) Closed-form

The best explanation: Closed form continuous PDEs are converted into discretized equations suitable for numerical SOLUTIONS. Analytical solution of this closed form PDEs will give continuous equations which can be used to GET the flow VARIABLE at any desired point in the DOMAIN.
