The 3DynaFS© Discrete Singularities Module was developed to simulate complex flows involving particles and/or bubbles, vortices, or other singularities. It uses a Lagrangian scheme to track singular elements such as bubbles, sources, sinks, vortex elements, and dipoles.

3DynaFS-Dsm© currently includes three sub modules:

The Vortex Element and PhantomCloud® can be coupled with 3DynaFS-BEM©.DF_MultiSap© can be used as a standalone program or can be coupled with other modules to extend their applications. DF_MultiSap© is also available as User Defined Function (UDF) for ANSYS Fluent as Discrete Bubble Model (DBM).

Other Available Modules:

  • 3DynaFS-Comp©- Compressible Module
  • 3DynaFS-Bem© - Boundary Element Module
  • 3DynaFS-Fsi© - Fluid Structure Interaction Module
  • 3DynaFS-Vis© - Viscous Module
