Data for 'Fluid flow in porous media using image based modelling to parametrise Richards' equation'

TC40_CA20F_sat50_mu_xa.mph: Example COMSOL model for fluid flow is soil for contact angle 20, mu cell problem in x-direction. To be opened with COMSOL v5.2 or later.

ImageBasedRichardsResults.mat: Matlab workspace file containing results from COMSOL models. To be opened with Matlab.
Structure names: Drying/WettingN - Data struture for either wetting or drying curve where N={0,20,60} indicates the contact angle in degrees.
Structure variables: 	Sat - Saturation
						CP - Nondimensional capillary pressure
						DimensionalCP - Dimensional capillary pressure
						K - Average velocity of water for unit drop in capillary pressure
						Kbar - Average velocity of water and air for unit drop in capillary pressure
						b - Average velocity of water for unit drop in combined pressure
						bbar - Average velocity of water and air for unit drop in combined pressure
Exp_NegHead - Experimentally measured pressure
Exp_Sat - Experimentally measured saturation
