Dear all, We are pleased to announce the release of Nektar++ v4.4.1. This release includes a number of further bug fixes and minor enhancements to the 4.4 release: **Library** - Remove m_offset_elmt_id and GetOffsetElmtId which fixed problems in 2D when quad elements are listed before tri elements (!758) - Remove the duplicate output of errorutil (!756) - Fix BLAS CMake dependencies (!763) - Fix interpolation issue with Lagrange basis functions (!768) - Fix issue with average fields not working with different polynomial order fields (!776) - Fix rounding of integer parameters (!774) - Fix Hdf5 output in FilterFieldConvert (!781) - Fixed extreme memory consumption of Interpolator when interpolating from pts to fld or between different meshes (!783) - Fix missing entriess in LibUtilities::kPointsTypeStr (!792) - Fix compiler warnings with CommDataType (!793) - Fix deadlock with HDF5 input (!786) - Fix missing entriess in LibUtilities::kPointsTypeStr (!792) - Fix compiler warnings with CommDataType (!793) - Fix ability to set default implementation in Collections and added an option to set eNoCollections in FieldConvert as default (!789) - Fix performance issue in ProcessIsoContour in relation to memory consumption (!821) - Fix performance issue with ExtractPhysToBndElmt (!796) - Fix available classes being listed multiple times (!817) **FieldConvert:** - Fix issue with field ordering in the interppointdatatofld module (!754) - Fix issue with FieldConvert when range flag used (!761) - Fix equispacedoutput for 3DH1D with triangles (!787) **NekMesh**: - Fix memory consumption issue with Gmsh output (!747, !762) - Rework meshing control so that if possible viewable meshes will be dumped when some part of the system fails (!756) - Add manifold meshing option (!756) - Fix issue with older rea input files (!765) - Fix memory leak in variational optimiser, add small optimisations (!785) - Check the dimensionality of the CAD system before running the 2D generator (! 780) - Fix uninitialised memory bug in Nek5000 input module (!801) **IncNavierStokesSolver** - Fix an initialisation issue when using an additional advective field (!779) **Utilities** - Fix vtkToFld missing dependency which prevented compiling with VTK 7.1 (!808) **Packaging** - Added missing package for FieldUtils library (!755) As always, if you encounter any problems please feel free to contact us on the mailing list nektar-users@imperial.ac.uk.
