Updates

Compiled setup, free-to-use licence

• One setup bundle per system, each with only the files it needs: Linux (x86_64) first, with Windows and macOS to follow.
• The program ships as compiled code only: the solvers were already compiled from Rust, and now every module of the application is compiled to native code as well.
• OxiPhys is now free to use under the OxiPhys licence, for commercial work, teaching and research. Versions up to 0.8.8 keep the MIT or Apache-2.0 licence they were released under.
• Code by others that ships with OxiPhys is listed with its licences in THIRD-PARTY-NOTICES.md, in every bundle.
• Fixed: with Python 3.9 and Matplotlib 3.9, the design workspace failed to draw sketches and part edges in the Matplotlib view.

Dimensions and sections placed on the sheet, detail views

• Section views: the cutting line, arrows and letter follow the pointer before the click; sections can be flipped from the inspector.
• Dimensions: snap rings on corners, ends and circles, the dimension drawn live after its two points; Shift on a circle gives a radius; dimensions on sections and details.
• Dimensions on the sheet are selected by a click, dragged to move and removed with Delete; Esc or a right click leaves any tool.
• Detail views: a circle, square or rectangle, or a freehand outline round part of a view, drawn again larger at an ISO 5455 scale, with the outline and letter on both views.
• Extra views fill the space under the standard views before new columns, so drawings keep a larger scale.

Drag drawing views, free rotation, swept hexahedra, help in the search

• Drawing views can be dragged on the sheet; the top and right-hand views slide along their projection line and the front view takes them with it.
• Free rotation: a trackball for Ctrl and drag, or for a plain drag when free rotation is on (View menu, the T key or Preferences); near the rim it rolls.
• Mapped hexahedra on parts made by one extrusion are swept from a quadrilateral profile: on round profiles the mean quality goes from about 0.5 to about 0.9.
• Meshes with folded cells are meshed again, and a folded mesh is refused before the solver with advice.
• The search field (Ctrl+K) finds help as well as commands: shortcuts, tutorials and the sections of the guides.
• A glass look with floating panes, vivid step tiles and colourful CAD and analysis icons.

Rounded look, command search, far less solver memory

• Rounded, anti-aliased controls with pastel light and dark palettes; San Francisco on macOS, the bundled Inter font elsewhere.
• Command search (Ctrl+K or Cmd+K) over the menus, the current toolbar and the themes.
• Side panels slide and the 3D view glides between orientations; a preference turns the transitions off.
• Assembly straight into the sparse matrix pattern: 3D peak memory down 2 to 7 times. Multigrid for iterative solves of 50,000 unknowns and more, about twice as fast.
• python -m oxiphys.benchmark measures solvers, memory and the desktop application on your computer.

OpenGL 3D view, turntable turning

• The 3D view is drawn by the graphics card (OpenGL) on Windows and Linux, with picking, hover, views, box zoom and picture export; it falls back to Matplotlib.
• Turntable turning by default: a horizontal drag turns about z, a vertical drag tilts.
• Windows: the mouse wheel reaches the view under the pointer; taskbar icon and shortcut fixes; DPI awareness.
• Parts drawn in the design workspace are named with z up; older projects keep their names.

Welcome window, plane choice, snapping

• A welcome window at start: new drawing, import CAD, examples, open or recent.
• Sketches ask for a plane: click a plane or a flat face, lit up on hover. Second features can be sketched on faces.
• Sketcher: automatic snapping, centre and 3-point rectangles, 2- and 3-point circles, patterns, merge points and more dimension kinds.
• Quicker 3D view while turning, panning and zooming.

Side panels fold to strips

• The navigator and the inspector fold to 44-pixel strips that keep a tile for every step.

The OxiPhys logo, a new setup program and layout

• The OxiPhys logo for the icon, the splash screen, the empty view and the setup banner.
• Setup with a banner, steps down the left, option cards, a progress bar and a finish page; OxiPhys keeps running after setup closes.
• A toolbar with the step's labelled commands, a navigator with search and an inspector on the right.

Compact layout for small screens

• Workflow steps move into the top row; the side panel can be hidden (F9) and messages wait until wanted (F10).
• A ribbon-style command bar in the design workspace, and a column of view buttons beside every view.

Part design and engineering drawings

• A design workspace for 3D parts: feature tree, command bar, property panel and a parametric sketcher whose relations and dimensions are solved together.
• Sweep, loft, rib, shell, draft, reference planes and a hole tool with ISO sizes.
• Engineering drawings on ISO sheets: views with hidden lines and silhouettes, sections, dimensions, notes, tables and a title block, exported to PDF, SVG, PNG or DXF.
• Mass properties, and documentation and validation for all of it.

Sketch features, materials library, OxiTunnel, tutorials

• A CAD-style camera with free rotation, roll and unlimited zoom, and three mouse styles.
• A new-project window with examples and six guided tutorials.
• Extruded and revolved bosses and cuts, fillet, chamfer, patterns and mirror.
• A materials library of 27 solids and 18 fluids with sources; elastoplastic static runs in the app.
• OxiTunnel for external flow, with drag and lift coefficients, validated for a cylinder and a sphere at Re = 20.
• Section planes through 3D results, and a Kannada interface.

Setup program, preferences, languages

• A setup program for Windows, macOS and Linux with every option first, a per-user install, update in place and an uninstaller.
• Light, dark and high-contrast themes, accent colours, interface size, unit systems and nine interface languages.
• Results as contours, dots, arrows, streamlines and moving particles.
• Local mesh controls on faces, edges and points, and picking by clicking in the view.

CAD import, geometry files, meshing methods

• STEP, IGES, BREP and closed STL import; imported parts combine with built shapes and touching parts are bonded.
• The .oxgeo geometry file, with imported parts embedded.
• Free, mapped and swept meshing, with a mesh quality report.

The desktop application

• A workbench that walks through analysis, geometry, mesh, material, loads and supports, solve and results.
• Solves run in a separate process; Stop keeps partial flow solutions. VTK, CSV and picture export.

The first release

• Finite element statics, modal, buckling, dynamics, plasticity, large deformation and contact.
• Finite volume flow with heat transfer, buoyancy and the k-omega SST turbulence model.
• A Python interface with an interactive console, Gmsh-based geometry, examples and references.
