extracting phase boundary coordinates
 

Hello,

I have a multiphase simulation where one phase of fluid is remaining on a wall (that i want to be as uniform as possible) and then the rest of the domain is filled with air.

I would like to extract the data in coordinates of the boundary between the phases so that i could build a map of this in some programming language.

does anyone know of a way to extract this data in the form of a cvs file or text file or a way to assess the thickness of the phase remaining on the wall?

thank you
