Recent Updates

New Features & Improvements

• Case Management

  • Added “Save As” functionality to allow saving case variants or relocating projects.

  • Enabled loading of zipped OpenFOAM cases, including embedded STL links for portability.

  • Mesh is now automatically displayed in the 3D viewer once loaded, streamlining the workflow.

• Licensing and Distribution

  • Introduced a simplified license manager to support client-specific activations.

  • Packaged and distributed Ubuntu binaries to the University of Sarajevo and Alihossein for deployment and testing.

System & Builder Enhancements

• Linux build system updated to embed resources (e.g., icons, styles) directly into the final zip package, ensuring complete portability.

Bug Fixes & Minor Enhancements

• Enhanced the “Find” feature in the Log File Viewer for better usability and case-insensitive search.

New Features & Enhancements

• Geometry Support

  • Splash now supports loading.OBJ files, in addition to STL.

  • Users can import multiple STL/OBJ files simultaneously for more complex assemblies.

• Simulation & Solver Enhancements

  • DDES case template added for advanced turbulence modeling.

  • Linear solver and algorithm settings exposed for advanced user control.

  • Convergence criteria are now configurable directly in the Run Controls panel.

  • Introduced a “Stop Simulation” button with behavior similar to Fluent.

• Post-Processing Improvements

  • Probes cleanup fixed: residual probes no longer persist after deletion.

  • Automatic patch selection when loading geometry, improving workflow.

  • Added a summary dialog to review simulation setup before launch (like Fluent’s “Check Case”).

• UI/UX & System Integration

  • Implemented real-time memory usage bar to monitor process load.

  • Help mode added – click on UI elements to receive tooltips/descriptions.

  • The advanced settings panel is finalized with detailed options.

  • Thermo-physical property editor enhanced with detailed inputs.

  • The boundary condition panel now includes:

    • Standard, Low-Re, and Roughness wall functions

    • Rotating wall boundary condition

• Visual Improvements

  • Local axes are hidden by default to declutter the 3D view.

  • Appearance theme now updates immediately upon clicking "Apply."

  • The action panel is resizable vertically for better usability.

Bug Fixes

• Resolved issue where Splash failed to detect the Linux environment, blocking meshing and solving.

• Fixed bug where boundary condition names weren’t recognized.

• Log Viewer: Implemented Find feature to search log content.

• Fixed UI inconsistency where icons were missing in the Linux v1.0 beta release.

• Resolved layout issue: mesh and solver up/down buttons were unresponsive.

Developer & Deployment Tools

• Added Poetry-based installer scripts to launch Splash in a virtual environment for cleaner setups.

Major Features Added

• Docker Integration

  • Seamlessly connected Splash CFD with Docker containers.

  • Docker terminals now launch in a separate window, allowing uninterrupted use of the main GUI.

• Mesh and Solver Workflow Enhancements

  • Mesh Quality Dialog: Added a detailed interface to inspect and validate mesh quality.

  • Residual Plot Viewer: Introduced real-time plotting of solver residuals with live updates.

  • Post-Processing Tools: Integrated tools to visualize forces, probes, yPlus, Q-criterion, and more.

• 3D Viewer Upgrades

  • OpenFOAM meshes can now be loaded and displayed directly in the interactive 3D viewer.

• UI/UX Improvements

  • Reorganized interface: Mesh and Solver controls moved to the left panel for better accessibility.

  • Patch properties now open instantly on double-clicking a patch name in the object list.

  • Boundary conditions for k, omega, and epsilon now come with intelligent defaults computed from U_inf or Re.

Bugs Fixed

• STL Loading Bug: Fixed issue where STL geometry failed to initialize until manually selecting a default case type (e.g., External Aerodynamics).

• Integrated Splash with Docker

• Enabled Docker to run in a separate window without interrupting Splash

• Added mesh quality dialog box

• Implemented residual plotting functionality

• Added live monitoring of simulation residuals

• Added option to choose multiple patches or single solid

• Improved default writing intervals for transient simulations

• Added support for binary STL files with single patches

• Implemented STL priority management using Up/Down arrows

• Added changeDictionary feature to ensure consistent patch types after meshing

• Added advanced mesh control tools

• Implemented serial simulation/meshing capabilities

• Added dialog boxes for additional geometries (box, sphere, cylinder)

• Implemented visualization of geometries in VTK viewer and Object list

• Connected inlet/outlet with boundary conditions for external flows

• Added support for wall boundary conditions when geometry touches ground
