CFxD is an integrated CFD application built to simplify engineering simulation. It combines the full workflow in one consistent environment—reducing manual steps and keeping projects organized.
Overview
CFxD supports a streamlined CFD process from model preparation to post-processing. The interface is designed to be approachable for new users while remaining efficient for experienced engineers.
Key capabilities
- Geometry creation/import and model preparation
- Mesh generation with statistics and quality checks
- Physics models and boundary-condition setup with sensible defaults
- Solver execution with convergence monitoring
- Post-processing: contours, vectors, plots, animations and reporting
Why CFxD
- Fewer manual steps and cleaner project organization
- Consistent workflow designed for practical engineering use
- Built-in documentation and contextual in-app help
Who it’s for
CFxD is intended for engineers who need reliable CFD results without spending time on repetitive setup and file management.

Licensing and Downloads
Demo
CFxD starts with a Demo license by default. Demo supports 1 CPU core and up to 250,000 mesh cells, allowing you to evaluate the workflow and core features before purchasing a Basic or Pro license.
Basic license
The Basic license supports up to 5 CPU cores and 5 million mesh cells. These limits apply to both monthly and annual Basic licenses. Start the purchase from CFxD on the computer you want to license so the application can supply its hardware details.
Pro license
The Pro license supports up to 100 CPU cores and 100 million mesh cells. These limits apply to both monthly and annual Pro licenses. The Pro license includes all Basic features and enables advanced workflows such as Rotating domain (MRF) and Conjugate Heat Transfer (CHT). It can be purchased from within the application or on the Buy page, and is activated on the machine after purchase.
Recommended workflow
- Download and install CFxD (Demo mode).
- Run tutorials/examples to validate the workflow for the target use case.
- Purchase and activate a Basic or Pro license from inside the app when ready.
