Preliminary frequency domain capability
Pre-release
The number of small features and bug fixes since the last release are probably too numerous to list or easily organize. High points include:
Frequency domain capability
New additions to the WEIS stack are RAFT (frequency domain solver), pyHAMS (potential-flow hydrodynamics), and MoorPy (pure python quasi-static mooring model). These have not yet been fully integrated with the WEIS design optimization workflow and have only undergone limited testing. Not yet ready for non-NREL use.
Direct usage of OpenFAST loads in design constraints
Design constraints around structural stress or buckling from extreme loads now use OpenFAST outputs for the blades and towers. Floating platform stress analysis from OpenFAST will be completed soon.
Improved optimization robustness
Many of the bug fixes and tweaks came from running sample problems and identifying issues. Many improvements have been made to the native WEIS code and even more to the supporting WISDEM and ROSCO tools.
