Actually when I reduce the timescale in CFX, 0.01s, the linear solver works fine. Maybe this is one way to avoid the failure in linear solver.

Thank you very much! in Fluent, I use all second order , see attached pic. For FLUENT, it is double precision. But for CFX, it is single precision. I can try double precision later to check the...

My question is that how can I reduce the residuals, then I can trust the results. At least 1E-6. Yes, pressure in the linear solver sometimes failed, and U-mom, V-mom...

Replies: 8 Convergence problem of CFX when comparing with FLUENT with same mesh Views: 2,032 Posted By guxin7005 Convergence problem of CFX when comparing with FLUENT with same mesh Hi, all, Thank you for reading my post. I am carrying comparison of 2D simulation between CFX and FLUENT. Results from FLUENT agrees well with experiments (residuals reduce to 3E-7). But CFX...
