What is pd in buoyantSimpleFoam
 
Hi

Could someone please explain to me what the field pd means in buoyant simple foam?

I understand p as the total pressure in this solver , not the static pressure.

I was expecting pd to be the dynamic pressure - but I was getting negative values for pd. My next assumption is pd has something to do with turbulence model.

Please give me a brief explanation that will help me study it in detail from books. Thank you

Hi, Prapanj, pd is dynamic pressure, maybe the following thread can help you to understant it, and in 1.6 version, pd is replaced by static pressure p.
