Hi,
I’m working on geological problem and I try to solve a gas transport across a soil.
To solve this problem, I want to modify the advection-diffusion equation and by the Fick law (diffusive transport) with porosity and permeability.
Also, I want to add the gas viscosity, and the pressure.
How can I perform?
(Moreover, do you know where I can find this file : h_transport_problem.F ?)
Thanks!
Welcome @RaphaelCSIR
I think this could be possible. However it is hard to assist you without the mathematical formulation you are trying to solve
Could you provide the PDE representing your problem?
This is not a file but an attribute of the problem class
Yes of course!
where P is the atmospheric pressure, k the soil permeability and u the hydrogen viscosity.
So how can I modified the advection-diffusion equation to fit with mine?
Thanks!
What is the \varphi variable here?
