Unsymmetric solver

Hi!

I am trying to solve my harmonic acoustic with an acoustic and structural region with an unsymmetric solver, but I cannot seem to get it done. Is there someone who knows how to do this in APDL or the mechanical R1 interface?

I looked into the book Acoustic Analyses Using MATLAB® and ANSYS, but their method is not available in ANSYS anymore. This is what is said: The displacement constraint can be applied to the nodes of acoustic elements
that have the displacement degrees of freedom activated, which can be
achieved by changing the option in the Acoustic Body in the row Acoustic -
Structural Coupled Body Options from Uncoupled, where the displacement
DOFs at the nodes are not included, to Coupled With Unsymmetric Algorithm
or Coupled With Symmetric Algorithm so that the displacement DOFs at the
nodes are included.

Kind regards,

Michael
