SHARPy: A dynamic aeroelastic simulation toolbox for very flexible aircraft and wind turbines

We are please to announce the release of SHARPy version 2.0!

✈️ This is a major release with a varied array of new features!

In SHARPy 2.0 the installation process has been modified to use pip (#175 thanks @DavidAnderegg!) with full details on how to install the new version in the installation docs.

Aside from this major change to the installation process, enhancements to the linear solver have been introduced. Now, you'll see what each input/output/state of the linear system corresponds to and how are the channels ordered.

🐞We have squashed a few bugs, an important one relating to flap inputs and sign convention in the linear vs nonlinear implementations (see #192 and #193)

⚠️ Reminder from v1.3: Unused/deprecated settings raise an error when you run your simulation! See PR https://github.com/ImperialCollegeLondon/sharpy/pull/148. This was found to be a needed feature to force users to clean up their settings, as conflicts could arise when solvers brought in new settings or dropped old ones. In addition, this means bye bye to simulations not performing as expected because of typos in the setting's name.

❓As always, please use the discussion board if you have any issues/questions using SHARPy.
