CADMAS‐SURF 3D2F - CADMAS-SURF/Multiscale-and-Multiphysics-Integrated-Simulator-for-Tsunami GitHub Wiki

CADMAS-SURF/3D2F is a software that can replace conventional model experiments of 2D wave-making channels in cross section, and was developed for application to wave-resistant design of marine facilities, allowing full consideration of the effects of free surface and breaking waves. With CADMAS-SURF/3D2F, water levels, velocities, accelerations, and pressures are calculated. Applications to various wave phenomena such as wave run-up, wave deformation due to reefs, wave propagation on uniform slopes with wave breaking, wave forces and wave overtopping on structures such as caissons, and reflection coefficient are being attempted.

  1. Analysis of complex flows characterized by free surfaces that behave as multivalued functions
  2. The Governing equations are the three-dimensional incompressible Navier-Stokes (Reynolds) equations and continuity equation
  3. Volume of Fluid (VOF) method is utilized for modeling the free surface
  4. To enhance the accuracy of shape approximation using a porous model
  5. The framework permits the placement of structures and boundary conditions at arbitrary locations within each cell
  6. For wave generation, the model incorporates two approaches: a wave-making boundary and a wave-making source
  7. Six types of wave functions, including Stokes waves, are employed to calculate flow velocity and water levels
  8. To minimize reflections, the model adopts Sommerfeld's radiation boundary and an energy dissipation zone
  9. The TimerDoor method is used for handling bubbles and droplets
