About Structural Analysis FEA 3D
Structural Analysis FEA 3D is a powerful civil, mechanical, and structural engineering tool designed to model, calculate, and simulate framed structures and three-dimensional components directly on your mobile device.
Designed for civil engineers, structural designers, mechanical engineers, architects, and students, it solves beams, 3D space frames, trusses, slabs, shear walls, and 3D mechanical parts with maximum precision and speed.
🏛️ 1. STRUCTURAL CALCULATION MODULE (2D AND 3D)
• Intuitive Modeling: Draw nodes, members, and panels on a millimeter grid with magnetic snap, or select from multiple engineering templates and benchmark models.
• Structural Typologies: Continuous beams, 2D planar and 3D space frames, pinned trusses, two-way slabs, and structural walls.
• Support Conditions: Fixed supports, pinned/hinged supports, and roller supports.
• Load Assignment: Point loads on nodes (Fx, Fy, Fz), uniform distributed loads on spans (w), and intermediate point forces.
• Material and Section Catalog: Standard library of steel profiles (IPE, HEB, HEA, W, tubular) and reinforced concrete sections (rectangular and circular), with the ability to customize elastic properties (E, ν, fy, density).
📊 2. DIAGRAMS AND INTERACTIVE 3D VIEWER
• Internal Force Diagrams: Bending moments (M), shear forces (V), and axial forces (N) with color coding and shaded areas.
• 3D Elastic Deformed Shape: Inspect structural behavior under load with real-time interactive scale amplification.
• 3D Force Vectors: Volumetric arrows and clear engineering symbols showing the exact direction and magnitude of each applied load.
• Serviceability and Drift Verification: Check maximum allowable deflections (L/360) and seismic inter-story drifts under international earthquake-resistant standards.
⚙️ 3. 3D SOLIDS AND STRESS ANALYSIS MODULE
• Parametric CAD Modeling: Generation of boxes, cylinders, and spheres with fillet, chamfer, extrusion, and boolean operations (union, cut, and intersection).
• CAD Import: View files in standard engineering formats (STEP, IGES, BREP, STL).
• Finite Element Analysis (FEA): Volumetric discretization and calculation of chromatic heatmaps with Von Mises equivalent stresses.
• 3D Export: Export your three-dimensional models in GLB format for visualization or sharing.
📑 4. PROFESSIONAL PDF CALCULATION REPORTS
• Automatic generation of complete technical reports ready to print or share.
• Includes formal cover page, summary of design assumptions, connectivity tables, applied loads, support reactions, maximum internal force envelopes, deflections, and structural verdict.
🔒 5. 100% LOCAL AND PRIVATE PROCESSING
• All matrix calculations and physics simulations are processed directly on your device's processor.
• Works completely offline without an internet connection. Your models and calculation reports never leave your phone or tablet.
💻 6. INTEGRATED TECHNICAL CONSOLE
• Command terminal for advanced users and developers looking to inspect files, run simulation scripts, and manage projects.
