Major Notes

Significant improvements to the unsteady TACS interface have been made with better incorporation of ESP/CAPS. Major bug fixes include a fix for mesh motion, grid coordinate derivatives, and additional unit testing concerning these features. Initial developments to mesh morphing based on shape changes are also included in the FuntofemShapeDriver and related classes. Several modifications have been made to the FUNtoFEM wrappers in FUN3D, mainly concerning grid coordinate adjoints and grid mesh deformation; these changes make this version of FUNtoFEM incompatible with versions of FUN3D which do not include these modifications. As of this release, aeroelastic, aerothermal, and aerothermoelastic implementations of the adjoint have been verified to at least $10^{-11}$ accuracy for steady problems without shape changes.

v0.2 Release

Advanced Python Improvements and Fun3d Unit Tests

The imports from the pyfuntofem module were significantly improved so all classes and methods are available from the top-level module. Now all relevant classes can be imported with from pyfuntofem import * or submodules model, driver, interface, optimization. Class methods, method cascading, and other advanced python features were added to the main funtofem model classes such as Body, Variable, Function, Scenario, etc. for shorter run scripts (on average ~45% fewer lines). New classes help build the coupled FUNtoFEMnlbgs driver easier such as TransferSettings, SolverManager, CommManager. Finally, copy constructor methods in Fun3dInterface are able to reload the fun3d Flow, Adjoint objects in real vs complex mode to enable FUN3D adjoint vs complex-step tests to be ran in unit tests now.

Pull Requests

• New badges, style updates to README.md by @bburke38 in #92
• Shorter Run Scripts using advanced python features, class methods, method cascading by @sean-engelstad in #96
• Fun3d Unit Tests with Fun3dInterface + TestStructuralSolver, and coupled tests in TestFun3dTacs @sean-engelstad in #97
