Hello All
I am trying to run a transient CFD analysis in Fluent with radiation (DO method), free convection (turbulent K-epsilon) and conduction. Initially I used 5 iterations per time step and the residuals of continuity was decent (even though the residuals increased as flow time increased). Then I tried the same case with 20 iterations per time step and the residuals had increased to up to and more than 1!! Can any of you guys have any clue what is wrong? Is it the Mesh??
Thanks
