It doesn't work to sample or probe the data from "kinematicCloud:UTrans" file

zhangxc0223 · September 3, 2020, 08:18

For a multiphase simulation, I have tried to put the code below into either “sampleDict” or “controlDict/functions/probes”.

Code:

        
fields
(
    U.air p kinematicCloud:UTrans
);

There are outputs for U.air and p but nothing output for kinematicCloud:UTrans. Also, I tried to use a quotation mark, and it doesn't work either.

Code:

        
fields
(
    U.air p “kinematicCloud:UTrans”
);

Is there suggestion on this? Thanks in advance.

Maybe it's caused by its type: volVectorField::Internal
Maybe sample doesn't support for Internal.

Could you figure out how to sample kinematicCloud:UTrans? I am struggling with the same issue.

Hi Armin,
you can try this tool, which can transform UTrans to a volScalarField.
After that, this new field can be sampled.

You are correct. At first thought, it should not actually pose a problem to add.
I have opened an issue, where you can follow up.
