MBDyn

The MBDyn Python Preprocessor simplifies the creation of input files for MBDyn simulations by bridging Python programming with MBDyn's input format. This project enhances the simulation workflow through two key improvements. The first transforms the YAML-based Rotorcraft Parametric Modeling tool into Python classes within the preprocessor, creating an object-oriented framework for rotorcraft modeling. The second integrates the preprocessor with Blendyn (a Blender add-on), enabling users to create, edit, simulate and visualize MBDyn models entirely within Blender. These enhancements make MBDyn modeling more intuitive and accessible while providing a seamless workflow for both pre- and post-processing tasks.

The Genetic Optimization Module for MBDyn seeks to integrate a genetic algorithm (GA) into MBDyn, a multibody dynamics simulation software, to enable optimization within simulation runs. As a super-element, the module will leverage MBDyn’s drive system—taking inputs from drives that expose simulation data and outputting optimized variables to other drives. Inspired by the mbdyn module’s structure, the project emphasizes a self-contained GA implementation in C++ to ensure minimal dependencies. The development is split into two phases: a 175-hour baseline solver with core functionality and a 350-hour fully-featured solver with advanced features and optional external library integration. This proposal targets the 350-hour project, aligning with the Google Summer of Code’s 12-week timeline (approximately 480 hours at 40 hours/week), delivering a robust optimization tool for MBDyn users.

The MBDyn Python Preprocessor aims to streamline the creation of input files for MBDyn simulations by bridging Python scripting with MBDyn's input format. Currently lacking support for all MBDyn entities, the preprocessor needs extension to cover all available entities. Additionally, integrating the preprocessor with Blendyn, a Blender add-on for post-processing MBDyn output, will provide a GUI based preprocessor for generating MBDyn input files. The project entails incremental development, starting with familiarization and planning, extending the entity library, managing model behavior, creating a model container, integrating with Blendyn, and finally, incorporating methods for aeroelastic models. These milestones culminate in deliverables that enable users to build entire MBDyn models using Python, including support for rotary-wing aircraft models, while ensuring completeness through thorough review and documentation.

Blendyn is one of MBdyn post-processing tools based on the Blender platform. It visualizes MBdyn output as a 3D system. However, the current Blendyn version is outdated since its last update is in 2017. In this project, we aim to flexible plotting engines and plotting features, and create a Live animation feature that visualizes MBdyn output in the real-time animation process. In addition to that, we also intend to make stress and strain visible for deformable objects.

<p>The convergence is assessed by calculating norm of the residual vector and currently the residual vector has many terms with different physical dimensions. Comparing different physical dimensions with each other does not seem to be a good idea.</p> <p>So the main idea of the project is to categorize various equations and variables on the basis of their physical dimensions and calculate the residual norms for each of the physical dimensions separately.</p> <p>Finally the convergence test will be modified.</p>
