I am working on IB-LBM and trying to code it using C++. Its open channel flow. First half of the domain is fine mesh and rest half is coarse mesh. I have copied the date on coarse and fine interface. However, there is no flow in coarse mesh. I beleive that this problem is because the code for Immersed boundary is not accounting it.
Immersed boundary code has two parts, body points and cell points. However, coarse mesh contains no body as body is defined in fine mesh only. So, i am failing to develop code for coarse mesh with no body to have the effect of Immersed boundary defined in fine mesh
I want to know how can i transfer the effect of Immersed boundary to my coarse mesh. Please see the picture for better understanding.
(there is no flow in the coarse mesh).
when we copy data from one mesh with immersed boundary to another mesh, it automatically delivers the influence of immersed boundary.
