Default Gas inlet pressure ramp rate

Hello,

I am trying to replicate the paper "effects of geometry and inconsistent mass flow rate on temperatures within a pressurized hydrogen cylinder during refueling", (Li et al).

The boundary conditions specify a mass flow rate of 0.025 kg/s, initial tank pressure of 2 MPa, initial gas temperate of 293 K and a final gas pressure of 35 MPa. However, a gas inlet pressure ramp rate is specified at 45 MPa. What does this ramp rate mean and how do I specify it considering I already have a mass flow rate inlet.

Regards,
Ross

Did you solve this problem at all, I am having a similar issue with specifying pressure ramp rates.
