pyva.systems.infiniteLayers.J_solid_porous

pyva.systems.infiniteLayers.J_solid_porous(xdata, res_ID, exc_ID)

Provide contact matrix J of solid - fluid intefaces.

The matrix corresponds to Eq. (11.75) 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 porous connection.

Return type:

DynamicMatrix
