ANALYTICAL + HERITAGE + PUBLIC-REFERENCE BENCHMARKED

SPACECRAFTTHERMALREIMAGINED

Browser-native. Physics-based. Benchmark-backed.

Browser-native spacecraft thermal analysis with benchmark-backed solver physics, geometry-native import and remesh workflows, orbital and radiation authoring, correlation review, and thermoelastic handoff. Benchmarked against analytical references, SAE 961452 parity cases, documented heritage reproductions, and named public-reference packs.

SECTION 01

The physics your hardware
demands

Every spacecraft thermal analysis comes down to one equation. We solve it with engineering-grade numerical methods — transient and steady-state — for every node in your thermal network.

REST contracts, API keys, webhooks, SDK validation runbooks, CLI smoke checks, and MCP validation paths support scripted and agent-assisted thermal workflows.

1111/12

Government Deployment Path

ITAR workflow controls, US data-residency gates, MFA enforcement, self-host foundations, GovCloud Terraform proof artifacts, and air-gapped validation checklists support government readiness work without overstating certification.

SECTION 06

Built intoyour program

Verixos becomes part of your engineering infrastructure — your models, your deliverables, your pipeline. The longer you run it, the more context it holds.

01

COMPLETE MISSION PROVENANCE

Every simulation run, what-if study, and design review comment is stored with the model that produced it. Your current thermal design traces back to PDR baseline — searchable, version-controlled, and attributable. The full engineering record, not just the latest export.

02

DELIVERABLE-READY OUTPUT

Export thermal analysis citations for CDR packages with benchmark compliance reports auto-generated. Verixos version, benchmark results B1–B10, and model hash are included in every report — so your review board gets everything they need without extra work.

03

NATIVE CI/CD INTEGRATION

Run thermal margin checks on every commit. Connect Verixos to GitHub Actions, GitLab CI, or Jenkins — get a pass/fail badge before hardware is committed. Thermal analysis moves at the speed of your software pipeline, not your review calendar.

04

SHARED ENGINEERING KNOWLEDGE

Custom materials, flight-heritage optical properties, mission bus templates, and node libraries are shared across your organization. Junior engineers work from the same benchmarked baselines as senior staff — institutional knowledge encoded into the platform, not locked in someone's head.

05

BUILT FOR THE NEXT GENERATION

The academic tier exists because the engineers who learn tools at university carry them into industry. Free access for students and researchers means Verixos is taught alongside the physics it simulates — the same way a generation of engineers learned MATLAB.
