I need to model a cylinder with hydrogen... r=.05 m and height = .5 cm I have modeled it as follows

1) Applied Navier Stokes Eqn. Initially the pressure is 3 atm in the cylinder.
2) At the outlet.. i have given a outflow condition as .01 m/s. The gas need to exit at this rate.
3) At the inlet.. I have given a inflow condition as a function of time .. Vin = (E-12*t^2 - 2E-08*t + 3E-05)/.089/22*7/(.05)^2 m/s

When i run this simple mass model i get the following error.

Error:
Time 0:
Failed to find consistent initial values.
Last time step is not converged.

Please help!
