Cadence FINE Marine 2023: Comprehensive CFD Software for Naval Architecture

Cadence FINE Marine 2023 is a state-of-the-art Computational Fluid Dynamics (CFD) software specifically tailored for the maritime industry, developed by Cadence Design Systems (formerly NUMECA International) . This powerful tool functions as a “virtual towing tank,” enabling naval architects and marine engineers to simulate and analyze fluid flows around complex geometries including ships, boats, yachts, submarines, and offshore structures.

Fine Marine is built on decades of solver development experience gained through close collaboration with the world’s top naval architects. It offers a highly automated, dedicated workflow for free-surface flow simulations, resistance and propulsion analysis, seakeeping studies, and maneuvering simulations. The software seamlessly integrates with other Cadence design tools, enabling multidisciplinary optimization throughout the product development cycle.

⚡ Key Features & Capabilities

 

???? Free Surface & Hydrodynamic Simulation

Fine Marine is specifically developed with total focus on flows involving free surfaces (water-air interfaces). Key capabilities include :

  • Highly accurate free surface capturing with adaptive grid refinement

  • Efficient free surface modeling considering both water and air phases

  • Appropriate turbulence modeling (from standard k-ω to advanced DES models)

  • Wave initialization and wave-damping strategies to prevent numerical reflection

???? Resistance & Propulsion Analysis

The software provides dedicated modules for evaluating vessel performance :

Application Key Capabilities
Resistance Standard analysis with C-Wizard automation; convergence booster speeds up calculations by up to 5x
Propulsion Actuator disks for quick trends; sliding grid approach for detailed propulsion analysis; ventilation and cavitation modeling
Self-Propulsion Accurate simulation of propeller thrust, torque, rotation rate, and power 

???? Seakeeping & Maneuvering

Fine Marine excels at simulating vessels in waves and performing complex maneuvers :

  • Seakeeping: Regular, irregular, or user-defined waves; grid deformation for high-amplitude waves; overset capability for complex motions

  • Maneuvering: Zigzag, turning circle, course keeping, pure sway, and roll decay 

  • 6DOF with marine-dedicated motion laws

⚡ C-Wizard Automation

The C-Wizard drastically reduces engineering time by automating complete CFD simulation setup through an intuitive, step-by-step process :

  • Resistance at low and high Froude numbers

  • Seakeeping analysis

  • (Self-)propulsion simulations

  • Planing hulls and Velocity Prediction Program (VPP)

  • Trim optimization

  • Matrix of simulations for PMM maneuvers (static drift, pure sway, pure yaw, roll decay) 

????️ Mesh Strategies & Grid Techniques

Fine Marine features a variety of mesh strategies for bodies with motions :

  • Weighted mesh deformations (ship trim and sink)

  • Sliding grids (propeller rotation)

  • Overset grids (complex motions, appendages)

  • Adaptive grid refinement for free surface during calculation
