How Diamond Enginexa Delivers Field-Ready Results
Complete Offline Architecture
Diamond Enginexa operates entirely without network connectivity. Every formula, material property, and calculation engine resides locally on your iOS device. The moment you need to verify pipe flow in a remote location or calculate thermal expansion in a basement workshop, the app responds instantly — no signal hunting, no data charges, no delays.
<Multi-Discipline Formula Engine
Eight engineering categories power your calculations: Mechanical stress analysis, Structural load distribution, Electrical circuit verification, Hydraulic flow computation, Pneumatic pressure checks, Thermal heat transfer, HVAC system balancing, and Materials strength lookup. Each discipline includes verified formulas with variable definitions, unit specifications, and worked examples that explain the math behind results.
Project Memory System
Version 4.0 introduces project duplication — copy an existing setup with all calculations and notes preserved, then modify variables for scenario testing. Each project maintains independent calculation history, allowing you to explore design alternatives without losing your baseline configuration. Field notes attach directly to calculation sets for context-aware documentation.
Verified Specifications
Critical Tools That Accelerate Your Workflow
8-Module Calculator Suite
Dedicated calculation interfaces for Mechanical, Structural, Electrical, Hydraulic, Pneumatic, Thermal, HVAC, and Materials engineering. Each module understands discipline-specific variables and outputs results in appropriate units.
Formula Library with Context
Browse verified equations across all disciplines. Every formula displays its mathematical notation, defines each variable with units, and provides a worked numerical example. Tap any formula to launch its calculator pre-configured.
Universal Unit Converter
Convert between Length, Area, Mass, Pressure, Force, Energy, Power, and Temperature units instantly. The converter remembers your last-used unit pairs and displays results with engineering precision formatting.
Drawing Calculator
Input geometric dimensions and material density to compute area, volume, and mass. Ideal for quick material quantity estimates in the field before formal CAD analysis.
Materials Database
Access density and strength properties for common engineering materials. The database provides quick reference data for steel grades, aluminum alloys, concrete mixes, and standard construction materials.
Offline AI Advisor
Ask engineering questions and receive structured checklists without internet. The AI runs locally using on-device intelligence, consuming daily token allocations to provide methodology guidance and calculation workflows.
