Steady state flow analysis - estimation of the flow using 'zone fluid steady-state'

Dear Itascans, is it possible to estimate flow in steady state using the command ‘zone fluid steady-state’ and ‘zone fluid unsaturated cutoff 0.0’?

Thanks in advance!!!

Do you mean you want to get a steady-state pore pressure solution with unsaturated cutoff? This is definitely possible. Try this example and in the fluid_flow.dat replace

model solve-fluid ratio-flow 1e-3

with

zone fluid steady-state

It works great. You just don’t get the pore-pressure history because it is solved in one step.

Thank you Jim. I tested and works very well, and the most important, very fast!!!
