Hi
I am using transient two phase darcy law for resin impregnation through a porous material. The porous medium (rectangular block) of certain porosity and permeability contains cylindrical porous tubes of a different porosity and permeability. The purpose is to study flow front variation in the inter-cylinder and within the cylindrical bodies simultaneously.
The entry of resin occurs at prescribed pressure and saturation while at the outlet vacuum is applied. All other surfaces of the rectangular block have no flux condition. The surfaces of the cylindrical tubes have NO FLUX condition as NOT APPLICABLE. No other boundary condition is specified for these tube surfaces.
The simulation runs into singularity error only after 0.06 seconds. I have attached the simulation file here for further review. Please revert with any possible solutions to this issue.
