Harmonic acoustic analysis#
This example examines a harmonic acoustic analysis that uses surface velocity to determine the steady-state response of a structure and the surrounding fluid medium to loads and excitations that vary sinusoidally with time.

The Sparse Matrix Solver is currently running in the in-core memory

avoid using the hard drive as much as possible, which most often
results in the fastest solution time. This mode is recommended if
enough physical memory is present to accommodate all of the solver
