How to Use a Custom Hydrodynamic Data File (.out) for a Current Energy Generator Model in OpenFAST?

[YuYuJou]

I am using the 15MW wind turbine as a template and modifying it to calculate a self-designed current energy generator model. Currently, I have converted the .LIS file output from ANSYS AQWA into a WAMIT .out file.

Do I only need to insert the data from the .out file into the .hst file to perform the calculations, without requiring the .1 or .3 files?

Dear @YuYuJou,

The HydroDyn module of OpenFAST cannot read frequency-domain potential-flow solution data from ANSYS/AQWA .lis or WAMIT .out file formats. Rather, HydroDyn expects such data to be stored in WAMIT .hst (for hydrostatic restoring) and WAMIT .1 and .3 (for radiation and diffraction) file formats. These file formats are documented in Chapter 4 of the WAMIT User's Manual, available online: https://www.wamit.com/manual6.4/Chap4.pdf.

Best regards,
