The pressure correction is an __________(a) explicit time-independent method(b) implicit time-independent method(c) implicit time-dependent method(d) explicit time-dependent methodI had been asked this question in unit test.The above asked question is from Incompressible Flows in division Incompressible Flows & Compressible Flows of Computational Fluid Dynamics

Answer»

Right choice is (c) implicit time-dependent method

To explain I would say: The pressure correction method is based on time. It uses time steps to move towards a steady SOLUTION for steady PROBLEMS. If the problem is transient it uses time steps to move to the desired interval of time. It is an implicit method as it solves all the equations SIMULTANEOUSLY.
