pyva.systems.infiniteLayers.I_porous_fluid
- pyva.systems.infiniteLayers.I_porous_fluid(xdata, porosity, res_ID, exc_ID)
Provide contact matrix I of porous-fluid interfaces.
The matrix corresponds to Eq. (11.73) in [All2009]
The I matrix defined the coupling coefficient for the same material, here !
When fluid and porous are exchanged J and I are interchanged. The response DOFs stay the same, because they defined the row index in the global allard matrix.
- Parameters:
xdata (DataAxis) – xdata for contact matrix definition, wavenumber or frequency.
res_ID (integer) – reponse ID of I matrix.
exc_ID (integer) – exc_ID of I matrix.
- Returns:
I matrix of solid porous connection.
- Return type:
