 January 6, 2012, 10:28 2D in Fluent Vs 2D in CFX #1 Senior Member   mohammad Join Date: Dec 2010 Location: Seoul, South korea Posts: 214 Rep Power: 9 Sponsored Links Hi everybody, I want to know that does the method we use in CFX for a 2D in FLUENT? I have solved a 2D model in CFX but it gives me floating point error in FLUENT.... As you may know, in CFX we just generate a mesh with two nodes in depth, and this will be our 2 D model....I know that FLUENT is able for 2D simulation...i just want to know that does the same model with 2 nodes-in-depth work in FLUENT or not... if not, what do you think might be the cause of error in my case? Thanks a lot

Therefore to run this case you should adopt any one of the following approache: 1. Use the 2-D mesh (better approach) 2. use the symmetry condition on both sides
