I'm using coupled solver to solve 3-D swirler flow..Inviscid solution with about 1.5M tetrahedral cells has converged. Viscous solution failed to converge specially the energy and the continuity residuals which became almost constant around the value 2.0x10E-03...Any advice is highly appreciated..
Re: Convergence Problem..!!
Try lowering the convergence parameters and try using different types of discretization schemes. Probabaly that will work.
