Digital Engineering Tools
Purpose-built software that turns REAH's engineering methods into reusable, scalable tools — so no problem is solved from a blank sheet twice.
Why Software
An engineering study solves a problem once. Software solves it every time after that.
REAH is built on the principle that engineering knowledge should compound: every analysis method we use — cooling-system sizing, duct-loss estimation, CFD case setup, test-data reduction — is a candidate to become a tool. The tools are then sharpened on real project work. This is how a small company avoids starting from a blank sheet, and how engineering hours turn into durable intellectual property.
Current Status
Status
REAH's tools are in development and used daily on our own engineering work. This page describes what exists and where it is going. Progress is published in REAH Labs.
What We Are Building
REAH CFD Studio's setup workflow: model regions are selected and mesh checks configured, then propeller, rotor, wheel and heat-source regions are assigned before the model is simulated. This reusable setup logic is what makes a simulation campaign repeatable rather than bespoke each time.
- REAH CFD Studio — an internal simulation front-end that takes a CAD model through upload, flow and heat setup, accuracy selection, solve and results review, for internal- and external-flow cases. In development and used daily on our own engineering work.
- Rotax Cooling Toolkit — fast, physics-based sizing of coolant radiators, oil coolers and ducts for Rotax-powered installations, from airframe category to subsystem checks. Every result is a labelled pass/fail verdict with margins, and the tool states its own limits: engineering estimate only, to be calibrated against vendor and test data. In development.
Rotax Cooling Toolkit development interface for sizing coolant radiators, oil coolers and ducts in Rotax-class UAV and light-aircraft installations.
- Simulation automation — version-controlled, reproducible CFD case generation and post-processing pipelines, so a simulation campaign behaves like a software build.
- Engineering knowledge systems — structured capture of methods, assumptions and results, designed so software can retrieve and apply them.
- Flight-test data systems — acquisition, reduction and comparison of test data against model predictions.
How We Build
- Every tool starts as an internal instrument used on real engineering work.
- Tools are versioned, tested and documented like production software, because they are.
- Physics first: no tool ships a number we cannot trace to a method, a source or a measurement.
Typical Customer Questions
- Can our recurring analysis workflow become a tool our own engineers run?
- Can simulation setup and post-processing be automated and made reproducible?
- How do we capture engineering knowledge so it survives staff turnover?
Evidence
Tool development is documented in REAH Labs with status labels: concept, in development, available.
Access
REAH applies these tools within engineering programmes today. Product access will follow defined validation and release gates.
- Software augments engineering judgment; every delivered result is reviewed by an engineer.
