3DynaFS© A CFD code for Bubble Dynamics, Large Free Surface Deformations and Ship Motion

Date announced: 13 Jun 2005

3DYNAFS© is a Boundary Element Method based Computational Fluid Dynamics (CFD) code designed for the simulation of three-dimensional unsteady incompressible fluid flows in the presence of free surfaces. The program can handle the dynamics of a single or multiple bubbles near solid boundaries or free surfaces, bubble dynamics near a submerged object and deformation in a non-uniform fluid flow the dynamics of free surface waves, and generation of surface waves by a floating or submerged body motion. 3DYNAFS© is being developed for cavitation studies on planing surfaces and propellers, and for ship / ship interaction, and surf zone modeling. It is being coupled with other general purpose codes such as the Mississippi State University Reynolds Averaged Navier Stokes code UNCLE and the Lawrence Livermore National structured Laboratories dynamics code DYNA3D.

The code is designed to solve three-dimensional fluid flow problems involving highly non-linear free surface dynamics, such as encountered in multiphase flows, ocean dynamics and time dependent interfaces separating two or more fluid phases. The program uses the Boundary Element Method that is highly efficient in studying fluid flows with large boundary deformations.

Additional configurations required by the user can be added upon request. DYNAFLOW, INC. can also customize the program by mutual arrangement.

2DYNAFS© is an axisymmetric version of 3DYNAFS©
HARDWARE: 3DYNAFS©and 2DYNAFS© are available for Unix and Windows environments.
