ExaDEM - v1.1.3

🚀 What’s New

✨ New Features

• Mixer example Introduced a new simulation example showcasing a particle mixer, useful as a reference case for studying granular mixing and testing boundary interactions.

• Examples with large vertex sets (#160)
  Added demonstrations with geometries containing many vertices, enabling users to test performance and robustness on complex meshes.

• OBBTree integration Added support for oriented bounding box trees (OBBTree) from Rockable. This improves collision detection efficiency and allows for handling more intricate geometrical configurations.

• Shape rescaling on import Added the ability to rescale shapes directly when reading shape files. This provides flexibility for reusing existing geometries at different scales without preprocessing.

🛠 Improvements

• Slot management Enhanced the logic for required slots, making slot handling more robust and reducing errors when defining simulation setups.

• Error handling refactor Centralized and factorized error management routines, simplifying the codebase and ensuring more consistent error reporting across modules. Use color_log::error and color_log::warning.

🐛 Bug Fixes

• ParaView STL export Fixed a bug when writing ParaView files containing STL meshes. The export process is now more reliable, preventing corrupted or incomplete outputs.

• MSP driver output files Fixed an issue in writing MSP driver outputs, ensuring correct file generation and avoiding data loss during post-processing.
