Question

The SIMPLE algorithm used for transient problems is __________

(a) implicit and iterative

(b) implicit and direct

(c) explicit and iterative

(d) explicit and direct

This question was posed to me by my school teacher while I was bunking the class.

Query is from Transient SIMPLE and PISO Algorithms topic in chapter Transient Flows of Computational Fluid Dynamics

Answer 1

Right answer is (a) implicit and iterative

Best explanation: For the implicit solution of transient flow problems, the SIMPLE, SIMPLER and SIMPLEC algorithms can be used to get the solution at each time-step. The solution is iterated until we get them converged at one time-step.
