CalculationX connects engineering analysis, project delivery, and technical procurement. Model systems in XPipe, XDuct, XFrame, XPsych, and XHeat; coordinate the work in Plinth; then manage materials, RFQs, supplier offers, and approvals in MatFlow.
Start with any app · Keep every workflow in one account · No installation required
Each app stays focused on its job, while CalculationX gives your team one place to move from technical decisions to coordinated delivery and controlled purchasing.
A visual pipe network calculator for water, glycol, oil, and other engineering systems. Draw supply and return piping, calculate pressure losses, and identify the index run.
Duct network analysis for supply, return, and exhaust systems with real fitting coefficient inputs, section-by-section losses, and critical path detection.
Modern steel frame modeling and analysis with visual editing, member force diagrams, design summaries, and report-ready results.
Interactive psychrometric analysis for HVAC processes. Resolve air states, visualize the chart, model common air-treatment processes, and export project reports.
Plate heat exchanger preliminary sizing and performance estimator. Size by geometry, recommended range, manual U, or vendor calibration, with full validation and sensitivity checks.
The delivery layer for CalculationX: organize engineering work, owners, dates, dependencies, risk, and project progress in one shared workspace.
A full procurement command center: RFQs, multi-supplier offer comparison, bills of materials, and supplier compliance — built for engineering purchasing teams running real supply chains.
Use the specialist app you need at each stage without losing the wider project context.
Model pipe and duct networks, frames, air processes, or plate heat exchangers with dedicated engineering inputs and transparent calculations.
See assumptions, governing paths, loads, losses, warnings, and report-ready results instead of relying on a black-box answer.
Use Plinth to organize owners, schedules, dependencies, milestones, progress, and the engineering work needed to close the project.
Use MatFlow to structure material variants, build BOMs, issue RFQs, compare supplier offers, verify compliance, and control approvals.
Start free. Upgrade when you need higher limits, private support tickets, or team-level support.
Modern tools for engineers who want speed without losing control of the calculation.
Runs in any modern browser. No desktop install, license dongle, or heavy setup before you can start working.
Inputs, assumptions, loss breakdowns, governing paths, and result tables stay visible so engineers can review the calculation.
Your calculations are saved to your account. Access projects from any device and continue work without moving files around.
Export calculation reports with consistent formatting, clear inputs, and results ready for engineering documentation.
