Any example for rock solid-fluid coupling triax?

Asked by Ziyu Wang

Hello,
As mentioned in the title, I want to study the evolution law of mechanical properties of rock under triaxial compression under fluid solid coupling. I know that flowengine should be used for my purpose.
But I don't know how to measure seepage characteristics, such as permeability and so on..So maybe some examples about rock fluid-solid coupling are help.

Best wishes.

Hello,

It is probably a good idea to start with the examples. We have an example showing how to measure permeability [1]

>So maybe some examples about rock fluid-solid coupling are help.

FlowEngine can be coupled with any material you like. If you want some kind of jointed crack rock model, you can use JCFpm. If you just want a cohesive rock then you can use CohFrictPhys.

Cheers,

Robert

Hello,Robert
I'm sorry to restart this problem. I have a little confusion about example[1]
In [1],The permeability is calculated by the following formula:
permeability = abs(Qin)/1.e-4
What is the meaning of 1.e-4?How to get this value.
