While performing a 2D simulation in Fluent 16.0, I am getting the following message:
"Update second order grid even though solver is detecting no motion for current time step"



What does it mean and how does it affect my solution?

Can you be more spesific about your case? For example is there any dynamic mesh or moving reference frames?

Hi,


No there is no dynamic mesh.


Its a simple 2D simulation problem for unsteady flow over a triangle in a fluid domain. The inlet temperature is set at 300 K and the triangle surface is set to 303 K. The top and bottom walls have free slip condition and the outlet is pressure outlet. The inlet velocity is 50m/s, density and viscosity of fluid is set to 1.

My guess was also something related to a dynamic mesh. I have no clue why you would see this message if not. Or maybe you are doing automated grid refinement?

Guys....I am so sorry...I did use dynamic meshing....my bad that I totally forgot about it...the simulation was running for over a day....


But is the message something that I should be worried about?
