number of digits

hey all.
I'm plotting some temperature profiles in CFD post, see attached. Ass seen the plot is very notchy because Fluent only calculates with 3 digits after the comma. Does any of you guys know how to configure fluent to calculate with more than 3 digits after the comma? Thanks Thomas |
If you are making XY-Plot, look in Plot>XY Plot > Axes > Precision.

Hi.
Is that in CFD-Post? I can't find the buttons you mention.. I've created a Chart where the data source comes from a Line that I've created in the section where I want to see the temperature profile. |
Soory my mistake, I put options for Fluent.
For CFD-Post look in to Chart > X-axis(tab). Uncheck 'Determine the number format automatically' and then you will be able to edit 'Precision'. |

hmm, I've tried that, see attached.. I think Fluent have only calculated the result with 3 digits. When I increase the precision to 7, it just gives me zeros after the third digit...
Do you know how to configure Fluent to be more precise in the calculation? Thanks |
Maybe, running in double precision may help?
|
it actually is with double precision...
|
Then I think this 'stair step' behaviour is due to the mesh in y-direction. Did you use boundary layer?
