Nas115 Fluid Structure Analysis in MSC.Nastran
Finite elements may be used for fluid-structure interaction analysis of
many engineering applications, and MSC.Nastran has several methods
that may be used to analyze problems with flexible or rigid structural
boundaries. Solutions for resonance and forced response are available for
arbitrary shapes. Capabilities include the ability to analyze internal cavities
such as those found in automobiles, trucks, airplanes, and submarines
using eigenvalue, transient, and frequency response structured solution
sequences (SOLs 103 and above). The fluid is modeled with CHEXAs,
CPENTAs, or CTETRAs by specifying PFLUID in field 7 (new field) of the
PSOLID entry. In addition, an acoustic absorber and an acoustic barrier
are available. This seminar provides an introduction to finite elementbased
fluid-structure interaction analysis using MSC.Nastran. Examples
of each major topic are supplied.
