RHXY Sim is an AI verification workspace for managing model files, condition setup, solver runs, result interpretation, and PDF reports in one browser project. It combines CalculiX 2.20-based results with AI explanations so first checks and iteration comparisons move faster.
Web analysis workspace
Natural-language condition setup
Reports and iteration comparison
How it works
Handle files, prompts, and outputs in one product flow.
Add project files
Add STEP, IGES, STL, or OBJ files to a project and review automatic mesh and quality status.
Enter case conditions
Describe conditions like "500N on top, bottom fixed, SUS304" and AI converts them into an analysis case.
Share results and reports
Review result maps, safety factors, and AI recommendations inside the project, then share by PDF or link.
Workspace Preview
The core screens you will actually operate in the browser.
Upload CAD file
Drag and drop STEP, IGES, STL, OBJ files. Gmsh auto-generates mesh.
Describe conditions
"500N on top, bottom fixed, SUS304" — AI converts to boundary conditions
Solver execution & status
CalculiX 2.20 solver runs. Convergence monitoring, automatic mesh quality check.
Review results & export report
Stress distribution, deformation, safety factors, design recommendations. PDF report download.
Key Features
Explore the core capabilities of RHXY Sim.
Multi-format support
Supports STEP, IGES, STL, OBJ and other major CAD formats.
Natural language conditions
Describe analysis conditions in plain English — AI converts automatically.
Validated CalculiX solver
Open-source FEA solver cross-validated against 18 benchmarks.
Auto mesh generation
Gmsh-based automatic meshing with quality assessment and convergence monitoring.
AI result interpretation
Analyzes stress/deformation/safety and suggests specific design changes.
PDF verification report
Auto-generates reports with assumptions, results, and recommendations.
Confidence ranges
Explicitly shows model accuracy limits and areas needing verification.
Fast iteration
Quickly compare multiple cases by changing conditions.
Beginner/Expert mode
Auto-adjusts UI detail level based on user expertise.
Work Scenarios
Software workflows prospective users can run directly in RHXY.
Run the first validation case
Add a file to the project, describe load, fixture, and material conditions in natural language, and review the first result.
Compare condition variants
Create variants by changing load direction, material, and constraints, then compare safety factor and displacement.
Get AI result interpretation
AI explains stress concentration, deformation trends, and areas needing additional verification, then suggests next review steps.
Share validation reports
Package assumptions, result maps, and recommendations into PDFs and links for team review or customer explanation.
Platform Support
Workflow Integration
Integrates with RHXY Render
When needed, overlay Sim analysis results onto Render scenes for technical explanation images.
NEXUS Engine — RHX.LAB
GPU-accelerated multiphysics solver core. Handles static/dynamic structural, heat transfer, and modal analysis in a single engine.
Data Security & Handling
Uploaded CAD files are automatically deleted from servers after analysis. User data is never used for AI model training. All transmissions are encrypted with TLS 1.3, and account/data deletion requests are supported.
RHXY Sim runs on RHX.LAB's NEXUS Engine. An integrated GPU-accelerated pipeline of Gmsh mesh generation, CalculiX solver, and AI-powered result interpretation.
