Dear qiong,

thanks for posting. Unfortunately, I cannot see anything directly from looking at your code and we cannot offer debugging of your complete application.
However, you could double-check that the boundary conditions are all set correctly and geometry indicators are set properly (maybe compare to another 3D example that uses an easier model).
Also, please consider to have a look here https://www.sciencedirect.com/science/article/pii/S0017931019361927.

We have a spring school coming up next year, where we could support you with implementing own setups and models (see https://www.openlb.net/spring-school-2025/ for more information).
