Calculation of local Reynolds number in OpenFOAM
 

Hello Foamers,

see this image please : https://drive.google.com/file/d/1bX9...0MWSAgfRa/view

How can I ;

1- Calculate width of this channel in each section of the channel?

and then

2- Allocate this value to all cells of that section in OpenFOAM?


I wanna to have a field of channel width like P field or something like that.

It is needed to calculate local Reynolds number as a characteristic length.

Any help or idea would be greatly appreciated.:)
