Hallo Friends,

I am putting a gas species through velocity inlet BC in a chamber.initially concentration of this species increases inside the domain(as obvious) but after many time steps concentration reduced to very negligible amount of concentration everywhere in domain and became constant and this become constant even before reaches equilibrium to high concentration in all domain.

it seems like any gas coming for inlet is stopped and neither another gas coming as still there little amount of processed gas species in chamber.it is visible from that concentration for processed gas is also not decreasing.

If some body have any idea.what could be the issue for this.Please share it.

Thanks
