Hello everyone,

I have implemented a SIMPLE segregated solver in Matlab to solve the lid driven cavity flow problem. I have checked the solution by running the same problem in Fluent.

So I just have a very general question, why is Fluent faster than my Matlab code?

I guess there are many answers for this question but what do you believe are the most relevant?

Convergence criteria and under-relaxation factors are the same for both cases as well as the initial conditions.
