[General] Importing Fluent data from a selected surface

godon · February 3, 2018, 12:13

Hi all,
I am running a simulation in Fluent, and want to obtain some contour maps in Paraview. My model is quite big (over 100 million elements), so I thought of exporting only the data from a single plane of interest for me.

I have tried with different formats available in Fluent (like Ensight, Tecplot, ASCII files), but so far haven't been able to read it in Paraview. In particular, when I try to export it in Ensight format, Fluent only allows me to select interior domains, and not data from a single plane.

From Fluent customer service they told me apparently i can't read data for post-processing from a single plane without the rest of the .cas file.

One alternative is to do it in Matlab (from an ASCII file), but considering the type of mesh i'm using and the specific plane of interest it would not be simple.

I expect this to be a common issue in large scale simulations post-processing, so I am sure there is a simple way of doing this in Paraview... Does anyone know how?

Best,
R.

I have had the same issue and was unable to find any solution.
Luckily I have access to FieldView. For FLUENT export you can use:
file export f-u-s
to export a surface.
