Connect two pipes with different space step
I need a two pipes described by equations:

But they have different steps in space (delta x).
I use HLLC Riemann solver.
For their connection, I use the following boundary conditions
(1)v[L+1] = (2)v[1]
(1)p[L+1] = (2)p[1]
(1)d[L+1] = (2)d[1]

(2)v[0] = (1)v[L]
(2)p[0] = (1)p[L]
(2)d[0] = (1)d[L]

[L+1] and [0] is ghost cells

In this case, I have a gap function of the velocity and mass flow.

Tell me how to implement such a connection of pipes with different steps in space?
