Thermal LBM

Hello everybody,

I’ve just started working on Thermal LBM! I want to choose the thermal model below:

A Novel Thermal Model for the Lattice Boltzmann Method in Incompressible Limit
Xiaoyi He, Shiyi Chen, and Gary D. Doolen
JOURNAL OF COMPUTATIONAL PHYSICS 146, 282–300 (1998)
ARTICLE NO. CP986057

But I find it is difficult to write the code only with the paper.
Could you please give me a suggestion? It would be high appreciated if send me any sample code.

Best wishes
Edward
