CFxD (ver. 2.11.06, July 12, 2026)

CFxD 2.11.06 Released
July 12, 2026

A new CFxD update is now available.

Version 2.11.06 introduces support for high-speed flow simulations with Mach numbers greater than 1, extending CFxD capabilities for compressible flow applications. This release also adds wall roughness settings in the Setup and Solution workflow, improves the user interface, updates the manual, and introduces a log-scale option for the convergence graph.

What is new in CFxD 2.11.06

  • All (NEW): High-speed model implemented for M > 1 flows
  • Setup/Solution (NEW): Wall roughness introduced
  • General (IMP): Manual updated
  • General (IMP): UI improved
  • Solution (NEW): Log-scale option implemented for the convergence graph

The new high-speed flow model expands the range of compressible flow cases that can be simulated in CFxD. The addition of wall roughness provides more control over wall boundary modeling, while the new log-scale convergence graph helps users evaluate residual behavior more clearly during the solution process.

CFxD (ver. 2.10.04, July 1, 2026)

A new CFxD update is now available.

Version 2.10.04 introduces the surface-to-surface (S2S) radiation model, extending CFxD thermal simulation capabilities for radiative heat transfer between surfaces. This release also includes updates to the manual, tutorials, and integrated help, together with further GUI improvements and extended convergence control options in the Solution stage.

What is new in CFxD 2.10.04

  • General (IMP): GUI improvements
  • General (IMP): Manual updated
  • General (IMP): Tutorial updated
  • General (IMP): Integrated help updated
  • All (NEW): S2S radiation model implemented
  • Solution (NEW): Convergence control extended

The addition of the S2S radiation model expands the range of thermal applications that can be addressed in CFxD, especially for cases where radiative heat exchange between walls is important. The extended convergence control provides greater flexibility in managing the solution process.

CFxD (ver. 2.09.01, June 9, 2026)

A new CFxD update is now available.

Version 2.09.01 introduces several important improvements to performance and workflow. This release includes code optimization, further GUI improvements, a new STEP export option in Geometry, and support for multi-domain conjugate heat transfer (CHT) simulations.

What is new in CFxD 2.09.01

  • General (IMP): Code optimization
  • General (IMP): GUI improvements
  • Geometry (NEW): Export to STEP file added
  • All (NEW): CHT multi-domain support implemented

The addition of STEP export makes it easier to transfer geometry for use in other tools and workflows. The new multi-domain CHT support extends thermal simulation capabilities by allowing conjugate heat transfer analysis across multiple solid domains.

New CFxD Benchmark Comparison Report

A new CFxD Benchmark Comparison Report is now available in the Documentation section.

The report presents a technical comparison between CFxD and Ansys Fluent for representative CFD applications, including:

  • Internal and external flows
  • Forced and natural convection
  • Compressible subsonic flow
  • Porous-media resistance
  • Transient vortex shedding
  • Non-reacting gas mixing
  • Rotating flow using MRF
  • Conjugate heat transfer

The report compares velocity, pressure, temperature, and species-distribution results using contours, profiles, and selected quantitative parameters.

This document is intended as a preliminary software-to-software benchmark demonstrating the consistency of CFxD results across a range of engineering flow and heat-transfer cases.
