High-speed interaction between two
structures or a structure and fluid requires simultaneous modeling
of large deformations of structures and shock propagation in
fluids.
Finite Volume better manages modeling
varying flow regime and boundary condition in fluids, because
numerical distortion related to Shape Function used in finite
element techniques do not exist. On the other hand modeling of
structural deformations can be done best by Finite Elements
because 3D Complexities are difficult to model by Finite Volume e.g
thin plates, beams etc.
fluidyn MP FSI
is a unique state of the art software which
involves simultaneous utilization of both Finite Volume and Finite Element
Techniques in their areas of strength. Therefore the
Fluid solver simulates the Fluid Flow in finite volume method,
whereas the Stress solver performs the Transient Stress Analysis in
the Structure using Finite element technique.
The unique automatic re-meshing algorithm takes care
of interaction between fluid and structure mesh. The boundary
conditions in Finite Volume and Finite elements are exchanged
automatically.
The solver may also be used for
problems involving either only Fluid Flow or Stress Analysis
Problems independently.
