You want to use the data as boundary profile? or you want to visualize it as solution data?

Then you need to stick to the interpolation data format in Fluent which is not straightforward if you have just few points or create a profile files and stick to the format in Fluent and apply interpolation method (like constant) or use CFD-Post to import user surface.

Dear friend,

Thank you very much for your help and your quick response.

I exported several velocity curve files at different times, and then I calculated the average velocity.

So, I think I have all the points of my domain.

I imported this file into CFD post, but I got this message

Dear Amine,

I export velocity contour files [x, y, z, v] at different times of post-processing under CSV extension.

Then I averaged the fourth column (velocity) of these files.

files in excel form.

Now I want to import this file which contains the average.

I hope that I have explained my problem.

You need to do that in the format CFD-Post is expecting. Check 8.7.1. Import Surface or Line Data into CFD-Post. It is best to export the Surface data for a time step to have all input already there and just to adjust it to the mean value.

 

The next time better to enable transient averaging in Fluent or CFX.

Dear Amine,

If possible, how can I activate the transient average in Fluent?

Respected Sir,

Thank you very much for providing some of your valuable time to answer my question. Now,

I read about the data sampling you tell me,

but I can not know the best value that I can put in the interval of sampling, I have:

a time step size 5e-5

interval [0, 0.3]

 

I saved the file every 50 steps with Autosave Time

Best regards,

Should I also put in the sampling interval 50?

Please.
