SPACECRAFTTHERMALREIMAGINED
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.
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.
Solar Flux
Direct solar irradiance at 1 AU. Computed for actual orbit geometry, shadow periods, and panel orientation.
Earth Albedo
Reflected solar energy from Earth surface. Varies with latitude, cloud cover, and surface type.
Earth IR
Infrared radiation emitted by Earth. Temperature-dependent, computed per orbital position.
Internal Dissipation
Heat generated by electronics, batteries, payloads. Time-varying power profiles per operational mode.
Feature
highlights
Purpose-built for spacecraft thermal engineers. Every feature designed around real engineering workflows.
Physics-Accurate Solver
Transient and steady-state thermal solving with RK4, Backward Euler, and Crank-Nicolson plus benchmark-backed analytical, heritage, and named public-reference evidence.
What-If Instant Replay
Saved analysis cases, parametric studies, sensitivity workflows, and fast compare surfaces keep design iteration in the browser instead of scattered across spreadsheets and exports.
Orbit Playback
Browser-visible orbital environments, eclipse behavior, beta-angle context, and radiation/view-factor review surfaces make thermal behavior easier to inspect and explain.
Radiation + Orbit Authoring
Configure LEO, MEO, GEO, and HEO cases with optics-aware orbital heat loads, beta-angle and eclipse context, and browser-visible radiation/view-factor workflow surfaces.
Geometry-Native Model Prep
Import CAD, stage cleanup and heal workflows, preserve geometry replacements across reimport, and keep geometry-derived provenance attached to nodes and review state.
Mesh / Remesh Workflow
Saved local remesh presets, mesh-readiness checks, quality summaries, and geometry-derived abstractions support analyst-facing geometry-to-thermal workflows.
Correlation + Evidence Review
Ingest datasets, compare runs, preserve review links and analyst context, and export machine-readable correlation and evidence packages for named workflows.
Thermoelastic Handoff
Produce Abaqus and NASTRAN temperature artifacts, adapter manifests, and reviewer-ready coupled-analysis packages without overstating native structural truth.
Studies, Reports, and Automation
Run what-if and parametric studies, save analysis cases, export reports and analysis packages, and automate the app through API keys, REST routes, and webhooks.
SDK / CLI / MCP Automation
REST contracts, API keys, webhooks, SDK validation runbooks, CLI smoke checks, and MCP validation paths support scripted and agent-assisted thermal workflows.
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.
Secure & Cloud-Native
Browser-native delivery with API keys, SSO/SAML paths, audit surfaces, self-host deployment foundations, and shared review workflows for real engineering teams.
Platform
capabilities
Browser-native thermal analysis with geometry-native model prep, automated orbital environments, saved studies, reviewable evidence, and automation surfaces. No desktop installs. No emailed `.sinda` files. No black-box licensing.
Transient & steady-state analysis on elastic compute
No local compute limits. Submit a job, get results. Supports fast transient and steady-state thermal solving for everything from simple CubeSat models to larger spacecraft analysis workflows.
Automatic environmental heat loads for supported orbit classes
Define orbital elements and the app computes beta angle, eclipse periods, Earth view factor, and the orbital heat-load context that drives thermal cases and review surfaces.
Shared review, comments, and model history
No more emailing .sinda files. Teams can review the same model with comments, review-state context, version history, diffs, and rollback-aware provenance tied to the thermal workflow.
REST API — the thermal analysis backend for your entire toolchain
Trigger thermal margin checks in your CI pipeline — fail the build if margins are breached. Automate parametric sweeps. Connect Verixos to your systems engineering workflow via REST API and Python SDK.
Curated space-qualified optical & thermal properties
Every material with beginning-of-life and end-of-life optical properties. Add custom materials with full property sets.
3D thermal model rendering with real-time results
See your thermal model in 3D with temperature color maps updating in real-time. Scrub through transient results like a video timeline.
From orbitto resultin one command
Define your orbit. Define your model. Verixos handles the physics.
REST API, Python SDK, CLI, and MCP are available today.Connect MCP-compatible AI agents directly to your thermal workflows through the Verixos Python package.
Run parametric sweeps from your coding environment. Iterate on material selection, orbit parameters, and geometry without leaving your editor.

Technical
specifications
An honest comparison with legacy thermal analysis tools. We complement, not compete — but we're building something fundamentally different.
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.
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.
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.
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.
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.
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.
Exceeds published SINDA/FLUINT parity thresholds on all implemented SAE 961452 cases
Benchmarked against the same analytical benchmark family used in validating legacy spacecraft thermal tools — and against a documented PharmaSat heritage reproduction chain.
