2D Simulations in CFX -- CFD Online Discussion Forums

March 3, 2014, 11:10	2D Simulations in CFX	#1
JuPa Senior Member Mr CFD Join Date: Jun 2012 Location: Britain Posts: 361 Rep Power: 14	I fully understand CFX is a 3D solver - to solve in 2D you need to extrude the geometry one cell thick (or if you import a Fluent .msh mesh CFX Pre extrudes it one cell thick automatically). However why is this such a problem? I hear many people complain that CFX doesn't do 2D. So what? Am I missing something? Wont a 2.5D simulation in CFX give the same results as a 2D simulation in Fluent? Can someone explain why people have issues with accepting that CFX does 2D simulations slightly differently?
