  Dynaflow releases 2DYNAFS©/ 3DYNAFS©
  by: OilOnline
  Monday, June 13, 2005

Jessup, MD ... 2DYNAFS©/3DYNAFS© is a suite of Boundary Element Method based Computational Fluid Dynamics (CFD) codes designed for the simulation of unsteady incompressible fluid flows in the presence of free surfaces. The programs can handle the dynamics of single or multiple bubbles near solid boundaries, free surfaces, submerged or floating objects, bubble deformation in a nonuniform fluid flow, the dynamics of free surface waves, and generation of surface waves by a floating or submerged body motion. 3DYNAFS© has recently been applied to 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 Laboratories structured dynamics code DYNA3D. 2DYNAFS© is an axisymmetric version of 3DYNAFS© with a user friendly Graphic User Interface (GUI).

The code is designed to solve 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.

2DYNAPVF© and 3DYNAPVF© are post-processing companions to 2DYNAFS and 3DYNAFS and enable computations of the field pressures and velocities.

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

OS: 2DYNAFS©/ 3DYNAFS© are available for Unix and Windows environments.
