Hello there,

I was wondering where the coordSys_ variable was defined? I see an instance of it in forces.C (more specifically, coordSys_.origin()), but I see in no other file where it is defined in. I am definitely missing a part of this puzzle.

running

cd $FOAM_SRC
grep -nr coordSys_

gives you a list of all the places where it is used and you can find where it is defined.
As it seems you are dealing with forces.C, I guess the closest to your case would be line 235 of of forces.H which reads:

coordinateSystem coordSys_;

and if you need to know more about it, you'll just search it in Doxygen which gives you this:
