Wave Propagation in Solids (BCs)

Wave Propagation in Solids (BCs)

(OP)
Hey!

I am trying to analyse wave propagation in a block of aluminium in Ansys APDL. I am giving a displacement signal out of a node and I observe the displacement at a receiver node. This worked quite well, but I did not figure it out out how to give acoustic boundary conditions to a solid body.

So, my question: How can I create acoustic boundary conditions to the walls of the aluminium cylinder (free and absorbing BCS)
I would be very pleased about an answer :)

With best regards,

Roman
