Release notes

This page contains information about what has changed in each new version of Maia.

v1.3 (January 2024)

💡 New Features

  • Algo module: add extract_part_from_family API to extract a submesh from FamilyName nodes

  • Algo module: add scale_mesh to scale the coordinates of a cartesian mesh

  • Algo module: add nodes_to_centers to interpolate FlowSolution_t from Vertex to CellCenter

🚀 Feature improvements

  • connect_1to1_families: manage Elements meshes

  • extract_part_from_xxx: transfer BCs on extracted meshes and manage structured meshes

  • partitioning: enable split of 2D/1D structured meshes

  • interpolation: allow input fields to be Vertex located in some cases

  • poly_old_to_new / poly_new_to_old : manage mixed elements

  • convert_elements_to_ngon : manage mixed elements

  • adapt_mesh_with_feflo: add an option to manage periodic meshes

🐞 Fixes

  • merge_zones: manage S/U GridConnectivity_t when merging U zones

  • add_joins_donor_name: prevent a crash when some GCs already have their DonorName

  • transform_affine : manage partitioned S zones and 2D meshes

  • transfer module : prevent a bug occurring when subset nodes have a dot in their name

  • convert_mixed_to_elements: prevent a bug occurring when multiple MIXED nodes are used

  • [v1.3.1] io: fix read of unstructured BCDataSet having a PointList

🚧 API change

  • extract_part_from_zsr: add transfert_dataset argument for easier transfer of current ZSR fields

  • convert_s_to_u: operate inplace (input tree is modified). Will return None in next release.

v1.2 (July 2023)

💡 New Features

  • Algo module: add adapt_mesh_with_feflo, wrapping Feflo.a to perform mesh adaptation

  • Factory module : add dist_to_full_tree to gather a distributed tree into a standard tree

  • File management: add read_links function to get the links from a CGNS file

  • File management: add file_to_part_tree function to read maia partitioned trees

🚀 Feature improvements

  • file_to_dist_tree: correct unsigned NFace connectivity if possible

  • wall_distance: add an option to take into account periodic connectivities

  • poly_old_to_new / poly_new_to_old : support 2D meshes

🐞 Fixes

  • merge_zones: fix unwanted merge of BCDataSet_t when merge_strategy is None

  • partitioning: fix global numbering of S BCDataSet + fix GC-related ZGC

  • isosurface: fix poor performances + better management of corner cases

  • distributed io: fix read/write of S meshes for data smaller than comm size

  • elements to ngon conversion: manage vertex located BCs

🚧 API change

  • redistribute_tree: remove default value for policy

  • wall_distance: remove families parameter

  • distribute_tree renamed into full_to_dist_tree

🔧 Advanced users / devs

  • Add a method to give a global id to any object in parallel

v1.1 (May 2023)

💡 New Features

  • Algo module: generate (periodic) 1to1 GridConnectivity between selected BC or GC

  • Factory module: generate 2D spherical meshes and points clouds

🚀 Feature improvements

  • generate_dist_block: enable generation of structured meshes

  • partitioning: enable split of 2D (NGON/Elts) and 1D (Elts) meshes

  • partitioning: copy AdditionalFamilyName and ReferenceState from BCs to the partitions

  • compute_face_center : manage structured meshes

  • merge_zones: allow wildcards in zone_paths

  • isosurface: recover volumic GCs on surfacic tree (as BCs)

  • transfer (part->dist): manage BC/BCDataSet created on partitions for structured meshes

🐞 Fixes

  • convert_elements_to_ngon: prevent a memory error & better management of 2D meshes

  • isosurface: improve robustness of edge reconstruction

  • partitioning: fix split of structured GCs and BCDataSet

  • merge_zone: fix a bug occurring when FamilyName appears under some BC_t nodes

🔧 Advanced users / devs

  • use new pytest_parallel module

  • transfer (part->dist): add user callback to reduce shared entities
