v3.0.4

Changes

• Fixed a bug for aerostructural optimization in parallel. The derivative of structural functions was not accurate due to an inconsistent serial/parallel convention in MPhys aero (DAFoam) and struct components (TACS). See detailed description from here. No updates are needed for DAFoam, but we need to update the dependencies: OpenMDAO, MPhys, and TACS.

• Fixed a bug for Multiple Patches in Aerostructural Coupling a83b5f3. Now we support having multiple design surface patches for Aerostructural Coupling.

• Added a fixed-point iteration adjoint solver 498874c. Now it works in serial only.

• Changed the multi-case setting f7dc586. Now it is done in MPhys.

Dependency update

Updated OpenMDAO to 3.25.0
Updated MPhys to 1.1.0
Updated TACS to 3.2.1

Backward-incompatible changes

One needs to update runScript.py for multi-case optimization. Check the latest setting from here

v3.0.3

Changes

• Fixed a critical bug (fBar seeds) in the DAFoamFunctions to make combined objectives such as L/D and multipoint have accurate derivatives a175e43
• Added an option ("comps") to allow selective actuator disk design variables 9f837b7
• Moved the coloring solution to the solve_linear such that coloring will not run for primal 20e112a
• Enabled more fvOptions functionalities a537446

v3.0.2

Changes

• Added a flag (ENV: DAFOAM_NO_WARNINGS) to suppress warnings such that one can see build error on the screen (no need to use 2> to redirect the errors/warnings) e043da9
• Printed the objective function when solving the adjoint equation d72aef6
• Added a new objective function (propeller power) 81bb716
• Improved the code coverage
• Allowed using the actuator thrust as the design variable 7d32447
• Increased the default adjPCLag to 1000 0cdfcf1
• Improved the field inversion interface 8c7d091

Dependency update

• Updated the pyGeo version to 1.12.2

Backward-incompatible changes

• One needs to update the FFD file interface for all v3 runScript.py. The old ffd_file argument is deprecated, and one needs to use a more general argument file and prescribe the DVGeo type, e.g., OM_DVGEOCOMP(file="FFD/wingFFD.xyz", type="ffd")

v3.0.1

This release added a few new features and fixed bugs.

Changes

• Coupled propeller movement in aerostructral cases fc34405
• Fixed the adjPCLag option f73b8da
• Updated field inversion functionality 8fc11d8
• Added Tensor flow C API fa1e928
• Changed the getForces function's default to designSurfaceFamily instead of allWallsFamily 8bc5696
• Fixed the Codecov badge issue 3222738

Dependency updates

• Updated the dependency versions for pyGeo, mphys, openmdao, tacs, and funtofem. Use the latest installation guide from here

Backward-incompatible changes

• The writeDeformedFFD function was deprecated for both v2 and v3 scripts. ac29d1a
• Updated the pyGeo APIs for setting design variables. The old API addGeoDVLocal and addGeoDVGlobal were replaced by addLocalDV and addGlobalDV in all runScript.py b8cfee7

v3.0.0

This major release integrated DAFoam and OpenMDAO for multidisciplinary design optimization through the Mphys interface.

• Developed an interface (mphys/mphys_dafoam.py) to Mphys and OpenMDAO for multidisciplinary design optimization. (6d24104)
• Update the dependencies' version. Check the new installation guide from here
• Add a findFeasibleDesign function to find the initial design variables to produce a feasible design before the optimization. This is an extension of the solveCL function and can handle more than one design variable and constraint (1889f5f)
• Fixed a bug in the mesh quality function. Now we can do optimization with a mesh quality constraint to avoid having poor mesh quality during the optimization. (995a580)
• Made the setOption more flexible in setting dicts. Now we can set the value in a dict one wants to update using the setOption function, without the need to use the entire dict. (995a580)
• Added an option to run low order primal for computing the Krylov solver preconditioner. (6d83cf6)

v2.2.10
