• 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.
