OpenFOAM utility: wdot
 
Hi guys,

Its an utility provided by OpenFOAM. In UG, we have this description:

Code:

wdot                        Calculates and writes wdot for each time
But what is wdot?
Thanks.

Quick answer: It's a utility: https://github.com/OpenFOAM/OpenFOAM...us/wdot/wdot.C
Try running:
Code:

which wdot
---------

edit: :rolleyes: Sorry... I misunderstood the question. Since you didn't specify "what is the wdot field?" - I didn't understand you had understood it was a utility.

As the source code indicates, it calculates:
Code:

St = Xi*Su
wdot = St*mgb

When searching in the source code, looks like PDRFoam has some answers:
Code:

turbulent flame speed field St

strained laminar flame speed field Su

Well... it's related to combustion... beyond that, I can't find more details.
