Plotting Residuals in Tecplot

Hello,
Does anyone know how to set continuity residuals or velocity residuals as part of Tecplot exported data? I know you can show the plot of residuals vs. iteration in the Fluent window or export the total model residuals to a .out file, but I am looking to plot the residual in Tecplot to see where my model is not converging. I am struggling with convergence and am hoping this will help show some areas where I need to set a larger mesh. Thank you! Marissa |

Residuals are not saved by default. You have to enable the storage of residuals in the expert options. You have to do two things. 1) turn on residuals. 2) set Fluent to also write residuals to the .dat file.
Type this into the TUI. /solve/set/expert n y n n For example it might look like this if you do it interactively Code:
/solve/set> expert use alternate formulation for wall temperatures? [no] n Save cell residuals for post-processing? [no] y Keep temporary solver memory from being freed? [no] n Allow selection of all applicable discretization schemes? [no] n Then you can go to data file quantities and under additional quantities select the residuals you want to write to the .dat file. Then you will be able to see the local cell residuals in tecplot. |
