cyclic injection

Please login with a confirmed email address before reporting spam

Hi all,

I would like to simulate the effect of wettability on hydrogen storage at the pore scale, and compare the effect of hydrogen recovery from storage at different contact angles by simulating the two-phase flow phase field structure after the calculation of one phase of hydrogen injection and drainage is completed, and then injecting water to drain the hydrogen gas and calculating again. I used to add two studies to simulate two phases separately. However, when simulating the second phase, there are cases that “the initial values are consistent, and the last time step does not converge”, or there are cases that the first calculated value is not used as the initial value, how can I correct my model?
