Computational Fluid x-Dynamics (CFxD)

CFxD 2.05.9 Released
April 3, 2026

A new CFxD update is now available.

Version 2.05.9 introduces several new features, interface improvements, and documentation updates. The main addition in this release is the implementation of conjugate heat transfer, extending the workflow to coupled fluid–solid thermal simulations. The update also adds several usability improvements in setup and post-processing.

• General (NEW): Pro license added.
• General (IMP): User interface improved.
• General (IMP): Manual updated.
• All (NEW): Conjugate heat transfer implemented.
• Solution (NEW): Monitoring point validation added.
• Setup/Result (NEW): Selection highlight added.
• Result (NEW): External data import added to Chart.

We published the videos with all current tutorials on YouTube.

We issued a small update (2.04.2).

• The new boundary condition with outlet mass flow is added.
• The vector plot capabilities are extended.

CFxD v2.04.0 — March 20, 2026

This release introduces major workflow upgrades and expands solver capabilities with transient simulations.

What’s new

• Geometry (NEW): Undo/Redo support for geometry creation.
• Mesh (NEW): Multicore meshing support.
• Setup / Solution / Result (NEW): Transient mode enabled.

Improvements & fixes

• General (BUG): Workflow bug fixed.
• Mesh (BUG): Skewness calculation corrected.

Update is available now from the app or from Download page.

Version 2.03.5 has been released. Visual UI bugs in the report generation have been fixed. Mesh refinement has been improved and significantly extended. CFxD now supports local refinement on selected surfaces and inside box/cylinder volumes, with multiple surfaces and volumes supported. The mesh cut view has also been improved. The manual, tutorial, and integrated help have been updated to reflect these new features.

A first tutorial has been recorded and shared on YouTube.

The new update (ver. 2.03.2) is available. The following features ar updated/implemented:

• Manual updated
• Surface structure in the Geometry unified
• Mesh box refinement introduced
• Porous jump to model porosity introduced

The new update (ver. 2.02.1) is available. The following features/fixes are implemented:

• Manual updated.
• Integrated help updated.
• Result: Color bar customization added.
• Result: Hidden elements re-appearing bug fixed.

We open a channel on Youtube and published first Intro video.

The new update (2.01.0) has been issued. UI improved, some small bugs fixed. Manual and tutorial has been updated. New post features introduced for the engineering analysis: average, maximum, minimum values, mass and volumetric flow rate and pressure force.
