Which algorithm (SIMPLE, SIMPLER, SIMPLEC, ...) is used as default in CFX, If we want to change the algorithm what is he procedure.

CFX uses a Coupled solver which means velocity and pressure are solved simmultaneously. SIMPLE* are all segregated solvers which rely on a pressure correction term and hence the pressure drives the velocity. Check CFX theory guide pdf. if you don't have it, it's easily downloadable. You can't change the solver algorithm, that's FLUENT's domain.
