NEXUS
ADVANTAGES

Flexcompute Nexus is licensed software that packages the same simulation stack powering Flexcompute's public cloud, now deployable inside your perimeter. Nexus keeps the cloud-grade developer experience while giving your security, infrastructure, and operations teams full control.
Deploy Inside Your Perimeter
Deploy Inside Your Perimeter
Install and operate Nexus entirely inside your data center, VPC, or airgapped environment. Customer-managed identity, networking, and storage, with no outbound dependencies on Flexcompute-hosted services.
Tidy3D and Flow360 on Your Hardware
Tidy3D and Flow360 on Your Hardware
Run Flexcompute's flagship Tidy3D and Flow360 solvers on infrastructure you already own. Engineers keep the same Python clients and Web UI, now pointed at a Nexus endpoint instead of the public cloud.
From Single Server to HPC Cluster
From Single Server to HPC Cluster
A three-tier architecture lets you start All-in-One on one server and scale out to PBS-managed GPU clusters with Apptainer workers and multinode MPI for large Tidy3D runs.

DEPLOYMENT
MODES

Nexus scales from a single All-in-One server to full HPC clusters. Solver containers are stateless and dynamically provisioned, so compute can live on-prem, in your cloud VPC, or across a mix.
All-in-One Server

All-in-One Server

Web, Compute, and storage on a single server, ready to run Tidy3D and Flow360.

PBS / HPC Integration

PBS / HPC Integration

Submit Flow360 solver jobs into your existing PBS-managed GPU cluster.

Apptainer Workers

Apptainer Workers

Rootless container workers for HPC environments with strict runtime policies.

Multinode MPI

Multinode MPI

Distribute large Tidy3D simulations across multiple nodes with MPI.

Private Cloud

Private Cloud

Run the full simulation platform inside your own VPC or on-prem environment, under your control.

DESIGNED FOR ENTERPRISE AND RESEARCH
Used by enterprise customers who need airgapped or data-resident deployments, research institutions with existing on-prem HPC, and teams running large concurrent simulation workflows.

FEATURES

Everything you need to run Tidy3D and Flow360 on your own infrastructure, with the developer experience of the Flexcompute cloud.

01 · Security & Control

Full control over security, data, and administration

Nexus is licensed software that you install and operate inside your own environment, with no dependency on vendor-operated cloud services. Ideal for organizations with strict compliance, data residency, or airgapped requirements.

  • Deployed in your data center, VPC, or airgapped environment
  • Customer-managed identity, networking, and storage
  • Meets strict compliance and data-residency requirements
  • No outbound dependencies on Flexcompute-hosted services
Full control over security, data, and administration
02 · Flagship Solvers

Runs Tidy3D and Flow360 on your own hardware

Nexus hosts Flexcompute's flagship solvers on infrastructure you already own. Your engineers use the same Tidy3D and Flow360 Python clients they know, against a Nexus endpoint instead of the public cloud.

  • Tidy3D for photonics and EM simulation (FDTD, Mode, Heat)
  • Flow360 for high-fidelity CFD simulation
  • PhotonForge and Tidy3D Python clients supported
  • Web UI and Python API, same developer experience as the cloud

03 · Flexible Deployment

From a single server to full HPC clusters

A three-tier architecture (Web Tier, Compute Tier, S3-compatible object storage) lets you start small and scale out. Solver containers are stateless and dynamically provisioned, so compute can live on-prem, in your cloud VPC, or across a mix.

  • All-in-One: Web, Compute, and storage on a single server
  • PBS / HPC integration for Flow360 on bare-metal GPU nodes
  • Apptainer workers for HPC-managed compute
  • Multinode MPI for large Tidy3D simulations
From a single server to full HPC clusters
04 · Collaboration

Centralized data and team collaboration built in

S3-compatible object storage centralizes simulation inputs, results, and metadata. Users and teams share projects and data without ad-hoc file transfers, while admins keep a single source of truth.

  • S3-compatible object storage for all simulation artifacts
  • Shared workspaces across users and teams
  • Centralized job and data management via Web UI
