I have a case where I would like to analyze the deflections of a structure due to an
impinging sound wave, and the subsequent re-radiation of sound due to this structural motion.
Can this be done in ANSYS?
Yes, using the Fluid-Structure Interface. The input below is a
transient analysis of a 100 psi pressure wave traveling in water and
impinging on an aluminum SOLID45 cantilever.
mp,sonc,2,59000 ! speed of sound in water in/sec
mp,dens,2,.0001 ! mass density of water
!!! apply fluid-structure interaction
!!! structural support
d,all,pres,100 ! 100 psi pressure pulse
!!! animate pressure over time
!!! animate structural motion over time
