Hi everyone

How to calculate the degree of saturation in gran cohesion easo/capillary/viscous model?
[Degree of saturation= a ratio of liquid to the total volume of voids in a porous material (soil) ]

thanks a lot and best regards

According to the following command in cohesion easo/capillary/viscous model :

fix id all property/global surfaceLiquidContentInitial scalar value
(value=value for the initial surface liquid volume in % of the solid volume)

and https://www.cfdem.com/forums/paraview-filter-void-fraction-estimation ( by richti83)
Do you think the following calculations are correct?

fix id all property/global surfaceLiquidContentInitial 0.1
volume_box=0.0000108
volume_sphere=0.000009
as a result:
volume_void=0.0000018
volume_liquid=0.1*0.000009

Degree of saturation= (0.1*0.000009) / (0.0000018)
