Chu is still having a problem:
Hi Robert,
>Have you tried decreasing the time step and or running the simulation for a longer duration? 
Yes,I tried.Decreasing the time step seems no effect ,but running the simulation for a longer duration (30k iters) looks better[1].Is it means that the FlowEngine works correctly?

In addition,I tried using flow.useSlover=0,and I got correct pore pressure field.But it caculate very slowly,and GS did not converge in 20k iterations.
