Hey

I see two ways you can approch this problem. You can use dynamic meshing with layering approach to calculate the leakdown time. Orelse keep it simple and change it into a multiphase problem if the flow rate and time is what you are after. But I don't think this can made into a steady case problem as you are dealing with a time dependent study.
