What is Ansys Aqwa
Ansys Aqwa is a hydrodynamic simulation tool used to analyze the motion and loading of floating and fixed offshore structures under waves, wind, and current. It is used by offshore and marine engineers for design and verification of platforms, FPSOs, moorings, and renewable energy devices. The product focuses on frequency- and time-domain seakeeping and diffraction/radiation analyses and is typically deployed as part of a broader CAE workflow that includes structural and system-level engineering tools.
Specialized offshore hydrodynamics
The software is purpose-built for marine and offshore hydrodynamics, including wave-structure interaction, seakeeping, and load prediction for floating bodies. It supports common offshore use cases such as platform motions, wave drift forces, and response in irregular seas. This specialization makes it more directly applicable to offshore engineering than general numerical computing environments.
Time- and frequency-domain methods
Aqwa supports both frequency-domain and time-domain simulation approaches, enabling early-stage screening as well as more detailed dynamic response studies. This helps teams compare operating conditions, sea states, and design variants using methods appropriate to the stage of engineering. The ability to move between domains supports validation and sensitivity checks within the same tool family.
Integration with CAE workflows
As part of the Ansys portfolio, Aqwa can fit into multi-physics workflows where hydrodynamic loads inform structural, fatigue, or system analyses. It aligns with engineering processes that require traceable simulation inputs/outputs and repeatable studies. This is useful for organizations standardizing on a single CAE vendor for model management and downstream analysis.
Narrower scope than CAD
Aqwa is not a general-purpose CAD or mechanical design environment, so geometry creation and detailed design changes typically occur in separate tools. Users often need additional software for parametric modeling, assemblies, and manufacturing-oriented workflows. This can add handoffs and data preparation steps compared with integrated CAD-centric platforms.
Steep learning curve
Hydrodynamic modeling requires domain knowledge (sea states, damping, added mass, mooring behavior) and careful setup to avoid non-physical results. New users may need training to select appropriate methods, boundary conditions, and numerical settings. Interpretation of outputs also depends on offshore engineering expertise rather than general simulation familiarity.
Licensing and compute costs
Commercial CAE licensing can be expensive for small teams, especially when combined with other analysis modules in an end-to-end workflow. Larger studies may require significant compute resources and solver time, which can increase infrastructure costs. Budget and procurement constraints can limit access compared with open-source numerical tools.
