Porous Media Flow Module
New Functionality in Version 6.4
Periodic Condition in Darcy’s Law Interface
A Periodic Condition feature has been added to specify periodicity between two or more boundaries. In the Periodic Condition node, it is possible to enter either a Pressure difference or a Mass flow between source and destination boundaries.
General
•
The Inlet boundary condition in the Darcy’s Law and Richards’ Equation interfaces now has the option to specify a Standard flow rate or Standard Flow rate (SCCM).
•
A new Power law permeability model specifies the permeability as a function of porosity.
•
A user-defined non-Darcian flow option has been added to specify the resistance coefficient β directly.
•
It is now possible to specify a pressure jump across a free-porous boundary within the Free and Porous Media Flow, Darcy multiphysics coupling.
•
A new Velocity Streamlines result template is available for all flow interfaces. Additionally, existing result templates have been updated to improve visual clarity.
•
Convergence has been improved for the Richards’ Equation interface.
•
The Fluid subnode, under the Porous Medium node, allows concentration as a Model Input to account for concentration-dependent material properties.
