Analysis Type(s): Mode-frequency Analysis (ANTYPE = 2) Element Type(s): Dynamic Fluid Coupling Element (FLUID38) Spring-Damper Elements (COMBIN14) Axisymmetric-Harmonic Contained Fluid Elements (FLUID81) Input Listing: vm154.dat Test Case A long cylinder is immersed in a circular hole as shown. The cylinder is separated from the containment surface by a frictionless, incompressible liquid annulus. A spring restraint is attached to the cylinder from ground. Determine the natural frequency f of the system based upon the hydrodynamic mass of the liquid annulus. ANSYS Verification Manual .
