Dear Yade community,
The more I learn about the implementation of PFV in Yade, the more impressed I
am by how cleverly it is mechanically coupled to the DE and by how efficient it
is at solving complex poroelastic

Hi Robert,
Imagine a compressible fluid flowing in a pipe.
The fluid density is not the same at the inlet and outlet due to pressure

Dear Bruno,
Thank you for the detailed response. At the pore scale of geomaterials,
I believe the assumption of local linearity

By sub-discretizing the flow path we could account for the gradient of
viscosity at the throat scale, indeed.
The fact is that even at the large scale we do not account for it. We h

Yes, the constant viscosity is an ok assumption since we are assuming
constant temperatures. If I decide to add thermal processes to yade, I
would adjust viscosity as a function

My point was that the change of viscosity by compressibility (not temperature)
is what we neglect

Ah, I think I understand now. You are saying that the only approximation
is the constant viscosity. I was just saying the change of viscosity of
geofluids as a function of press
