The Poroelastic Waves (pelw) interface (
), found under the
Acoustics>Elastic Waves branch (
) when adding a physics interface, is used to compute the displacement field and acoustic pressure fluctuation in porous materials with propagating poroelastic waves. Dedicated
Multiphysics Couplings exist that define the couplings between fluid, solid, and porous domains.
When the Poroelastic Waves interface is added, these default nodes are also added to the
Model Builder:
Poroelastic Material,
Porous, Free, and
Initial Values. For 2D axisymmetric components, an
Axial Symmetry node is also added.
Then, from the Physics toolbar, add other nodes that implement, for example, boundary conditions and sources. You can also right-click
Porelastic Waves to select physics features from the context menu.
The Label is the default physics interface name.
The Name is used primarily as a scope prefix for variables defined by the physics interface. Refer to such physics interface variables in expressions using the pattern
<name>.<variable_name>. In order to distinguish between variables belonging to different physics interfaces, the
name string must be unique. Only letters, numbers, and underscores (_) are permitted in the
Name field. The first character must be a letter.
The default Name (for the first physics interface in the model) is p
elw.
