Improvements in OpenFAST floating model
- Update OpenFAST input files for v3.5.1 release API changes
- Floating tower damping reverted to 1.0% to resolve numerical instabilities. There is a good deal of uncertainty about the true value here as it is normally determined experimentally. Comments to this effect have been added to the Wiki entry.
- Update the second-order potential-flow wave excitation of the VolturnUS-S platform. #137.
