Importing ANSYS AQWA diffraction results for multiple bodies (N = 3) into QBlade WAMIT format files
Hello everyone,
I am currently working on a hydrodynamic coupling workflow between ANSYS AQWA and QBlade on the floating offshore wind turbine supported by the Triceratops platform (contains 3 BLS) and seek guidance on the correct WAMIT-format representation for multi-body diffraction-radiation data.
Problem Description:
I performed a diffraction-radiation analysis in ANSYS AQWA for a FOWT supported by a triceratops platform consisting of three bodies (N = 3). From AQWA, I obtained the following hydrodynamic results:
- Radiation forces
- Added mass matrices
- Radiation damping matrices
- Sum-frequency QTF’s
- Difference-frequency QTF’s…these results are available for particular BLS in tabulated Excel form.
QBlade, however, requires hydrodynamic input strictly in WAMIT-compatible file formats. While QBlade example files and documentation primarily demonstrate single-body (N = 1) cases, my platform involves three hydrodynamically coupled bodies.
The objective is to correctly convert ANSYS AQWA diffraction–radiation results for a three-body floating system into WAMIT-format files that are fully compatible with QBlade’s hydrodynamic solver.
Kind regards,
Divyadeepsinh
