Hi!

I am attempting to do a Richardson Extrapolation where I need to find the representative mesh size h which is defined as the following equation,

I made my mesh with Fluent Meshing and I need to know where I can find the volume of the cells.

 

Best regards, Johanna

If you're in Fluent initialise the model and look in the Mesh part of Contours.

Sorry, but I do not follow.

[Rob]

You wanted to know the cell size - you can plot in the Fluent solver in Contours.

I am guessing this is the one you are thinking about? I hoped that there would be one more accurate that would give a specific number so that you don´t have to guess what shade of the colour it is?

[Rob]

Turn node values off to see the values for the cell and not smoothed may be helpful.  If you want you can export ASCII data from File>Export but visualising that will be fun.

Alright, thank you!
