A new Poroelasticity multiphysics coupling between Solid Mechanics and Darcy’s law has been introduced. When adding a Poroelasticity interface in version 5.2a, the two separate physics interfaces and the multiphysics coupling will be created. This will give access to all functionality available in the constituent interfaces. As an example, it is now possible to model poroplasticity.A new Gravity feature is available in the Darcy’s Law, Richards Equation, and Fracture Flow interfaces. The Gravity feature defines a volume force on the fluid due to the gravity in all the domains where the interface is active.Two formulations are available to specify Darcy’s velocity field under gravity: the Acceleration (default) and Elevation formulations. When the Acceleration formulation is selected, define the components of the gravity acceleration vector, while the Elevation formulation defines a reference elevation for the water table.The Richards’ Equation interface in 2D and 2D axisymmetric geometries now generates a new 2D Plot Group called Flownet. This plot combines a streamline plot for Darcy’s velocity field and a contour plot for the pressure head variable.
