pyva.systems.infiniteLayers.J_solid_fluid
- pyva.systems.infiniteLayers.J_solid_fluid(xdata, res_ID, exc_ID)
Provide contact matrix J of solid - fluid interfaces.
The matrix corresponds to Eq. (11.71) in [All2009] When solid and fluid 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) – response ID of matrix.
exc_ID (integer) – excitation ID of matrix.
- Returns:
J matrix of solid fluid connection.
- Return type:
