hi,
im running a case, where gas is flowing from two inlets into one small pipe. Inlets and outlets have micrometer dimension. The mesh seams fine if i use checkMesh.

Now my problem:
The time step continuity erros gets quite lare after approx 10 timesteps and the simulation convergerges, no change in pressure and velocity anymore although the simulation is definitely not finished. Attached you find u and p file from the 0 folder
