Hey all,

Here is a conceptual question:

Lets assume that there is a DFN model (particles that are attached to its 
neighboring particles via springs) and we inject fluid into one of the pore. 
Now the injected fluid will cause a change in the pore volume. This change in 
the pore volume will convert to a  change in pore pressure via the fluid bulk 
modulus. The change in pressure will cause the pore to expand. 

Now if the fluid bulk modulus was small (1e5 N/m^2) then the pressure would be 
small and the pore would not expand much. However, if the fluid bulk modulus 
was big (1e10 N/m^2) then the pressure would be big which will cause the pore 
to expand alot. However, because we inject fluid in the pore, we know the exact 
new volume of the pore. 

So how do we get the pore volume to match with the 'theoretical' pore volume 
without using the fluid bulk modulus as a calibration parameter?
