The Poroelastic Storage node adds Equation 4-1 and Equation 4-4 (excluding any mass sources). Use it to define the fluid and porous media properties, including a storage term to account for the Poroelasticity multiphysics coupling.

The settings are the same as for the Shell Properties section of the Richards’ Equation Model node.

The settings are the same as for the Storage Model node except a gas constant type is not required. There is also an option to define the fluid compressibility.

Select the Compressibility of fluid χf (SI unit: 1/Pa). The default uses values From material as defined by the Fluid material selected. For User defined the default is 4·10−10 1/Pa.

The settings are the same as in the Matrix Properties section under Fluid and Matrix Properties.
