BeidPrep

I designed BeidPrep as a completely free, Python-based tool to make high-fidelity Finite Element Analysis accessible to everyone. Developed specifically for the OpenRadioss community, it eliminates the manual complexity of text-based card editing, so you can focus on the physics of your model rather than the formatting of your files.

Why BeidPrep?

High-end simulation tools often come with restrictive fees, but I believe professional-grade model preparation shouldn't be gated. I created this tool to transform the "text editor headache" of open-source solvers into a modern, GUI-driven experience at no cost.

Core Capabilities

• Intelligent Card Editor: A structured interface for starter and engine cards featuring built-in field validation and dynamic visibility logic.

• Smart ID Filtering: Advanced cross-referencing ensures you only link appropriate IDs (e.g., Material IDs for material fields), preventing common simulation crashes.

• LS-DYNA Conversion: A functional importer for .k files, allowing you to open LSDYNA mesh models and convert them into the OpenRadioss files.

• AI-Powered Extensibility: Integrated Gemini Flash 2.5 logic allows the program to "learn" new cards by scanning documentation and generating JSON templates automatically.

• Visual Selection & Verification: High-performance 3D visualization via PyVista, enabling direct node and element picking for the creation of boundary conditions and contacts, hiding or isolating parts or elements.

• Engineering Efficiency Tools: Native support for Excel spreadsheet data-pasting and a specialized Plot Digitizer for extracting material data from images.

Legal Disclaimer & Terms of Use

BeidPrep v1.0 is currently in Beta and is provided to the community as free software "as-is".

By downloading and using this software, you acknowledge the following:

1. No Liability: I assume no responsibility or liability for any errors, model inaccuracies, or engineering failures resulting from the use of this tool.

2. Engineering Judgment: This software is a productivity aid and does not replace the requirement for professional engineering judgment and thorough verification of simulation inputs and results.

3. Beta Status: As a Beta release, you may encounter bugs. I encourage your feedback to help improve the tool, but I provide no warranties regarding its performance or stability.

BeidPrep 1.0 Feature Walkthrough: AI Card Import & Mesh Management

1. AI-Assisted Material Generation: Demonstrates the ability to automatically generate solver-specific material cards (like Radioss /MAT/LAWS) directly from web documentation into the BeidPrep library.

2. Property & Function Management: Walkthrough of setting up advanced solver parameters, including dynamic /FUNCT curves and penalty contact interfaces (/INTER/TYPE2).

3. Rigid Body Setup: Shows the manual creation and allocation of RB2 constraints across structural nodes.

4. Export Readiness: Concludes with exporting the fully pre-processed model, complete with all solver cards, directly into the target .k format for crash analysis.

Midsurface → Mesh in One Workflow

1. Body-in-White Midsurfacing: Extracts a clean midsurface from a large, thin-solid automotive component in under 10 seconds.

2. Topological Healing: Demonstrates dynamic edge seeding to mathematically weld disconnected free edges and ensure absolute topological continuity.

3. Algorithmic Mesh Control: Resolves poor mesh quality areas by switching to specific meshing algorithms (Algorithm 6) and tuning the fallback quality gates for quad-dominated results.

4. Curvature-Based Refinement: Highlights automated edge deviation controls to ensure the 2D mesh strictly adheres to complex geometric curves.

Automating 320 Washers & Rivet Connectors in 9 Minutes

1. Complex Geometry Handling: Extracts midsurfaces from a 14-component wing section, easily handling challenging features like chamfered holes.

2. Automated Washer Splitting: The geometric engine mathematically scans the skin, identifies over 300 specific rivet holes, and automatically applies washer padding across the entire assembly.

3. Structured Mesh Generation: Automatically generates a high-quality, structured quad-dominated mesh perfectly aligned around the newly created washer topologies.

4. Multi-Layer Fastener Automation: Discovers aligned holes across the assembly and automatically generates RB2 spiders and RB3 shanks to rigidly connect all overlapping components.
