Coupling LBM code wirtten on c++ with Yade

Hi,

You have one short example here: https://yade-dem.org/doc/FEMxDEM.html.

In this case, use is made of a common Python interface to couple YADE with another code. From my understanding, this is maybe the most convenient way to do things, at least from the YADE's side.

One possibility then would be to embed your LBM C++ code into Python, following the Python standard [1] and/or the dedicated Boost library [2] (by the way, this is how YADE "turns" from C++ to Python)

Maybe not an easy/small task to do, depending on your coding skills.

Thanks Jérôme Duriez, that solved my question.

Hi,
Coupling via python will make it more flexible and most likely less
efficient.
Integrating your code regardless of python is not something to disregard.
I'm not pushing in any particular direction, just pointing out that there
are various viable options which should be considered.

Thank you so much for you response. May I get more information about Integrating the code regardless of python.

FlowEngine is a fluid solver which is part of yade and does not communicate
through python at any point, yet reading it is not an easy thing.
The first step for c++ integration is to understand the logic of yade
engines. I'll be glad to help if you have more questions on this.
