momentum Exchange BounceBack

Palabos General
#1

I have found that there is an exchange momentum dynamics in palabos.
And it can be found in the examples/codeByTopic/bounceBack/computeDrag.cpp

But when I looked into this dynamics, MomentumExchangeBounceBack, I found many lines noted that “//Yields 0”.
What does this mean? This function has not been finished yet?

Thanks,
Maggie

Dear Maggie,

These comments ("///Yields 0") just mean most of the times that the specific function returs 0. The code for MomentumExchangeBounceBack is finished and you can use it as the “computeDrag.cpp” example demonstrates.

Best,
