Version 3.2.0

28/05/2021

• Highlights / General changes:

  • Full support of CPACS 3.2
  • TiGL 3.2 is shipped with OpenCASCADE 7.4.0 and is now compatible with pythonOCC 7.4.0. This includes all TiGL releases and Conda packages.
  • Improved computation speed of wing cell geometries.
  • Implemented cell definition with contour coordinates. This feature will be part of CPACS 3.4.
  • A new curve / curve intersection algorithm. This is used e.g. for the computation of curve network interpolation and was necessary due to a regression in OpenCASCADE 7.4.0. The new algorithm is designed to find all intersections between two curves within a user defined tolerance.

• New API functions:

  • New function ::tiglWingInterpolateXsi, that generalizes the functions ::tiglWingComponentSegmentGetSegmentIntersection and ::tiglWingComponentSegmentComputeEtaIntersection. Both old functions are now deprecated.

• Fixes:

  • Fixed fuselage walls transformation that did not respect the fuselage transformation before.
  • Fixed fuselage profiles, that had different positions than y=0 at start or end point.
  • Fixed crash, if first guide curve point is (0,0,0) or last point is (0,1,0).
  • Fixed wrong position of trailing edge device borders, if referenceUID is referring to a segment.
  • Fixed a bug in ::tiglWingGetUpperPoint and ::tiglWingGetLowerPoint, if the leading edge has zero size.

• Python Bindings:

  • The tigl3 Conda packages depend not on pythonOCC-core 7.4.0. If you plan to migrate your code, please notice that pythonOCC and TiGL don't use OpenCASCADE handles anymore. For more insights, please see here: tpaviot/pythonocc-core#583
