Release notes

v3.1.0 (April 11th, 2024)

Features:

Added Streamline and Vector visualization to Python Plots
Implemented variable power input to the Discrete Port and Coaxial Port
- Simultaneous excitation has a single input that affects all ports while in Sequential excitation cases each port has its own power input window
Added ability to define Port Capacitance instead of reactance to the Discrete Port to allow frequency dependent complex part of port impedance
- This allows to define RFID chip resistance and capacitance without the need of a separate lumped element

Improvements:

CENOS now supports FreeCAD v0.21.2
- To use newer versions of FreeCAD, the user needs to manually download the installer for FreeCAD and specify the path in Settings to the new installer. CENOS needs to be restarted for changes to take into effect

Bugfixes:

Current Density now appears in the Result Field dropdown in its own Python Plot tab
Fixed negative dielectric losses appearing in cases with a defined port reactance
Fixed radiated power being larger than the previous default input power (1 W) in cases with a defined port reactance

Features:

Updated Python Plots to include more results
- Added Electric and Magnetic Field visualization
- Added Surface Current Density visualization when using real conductors
- Added Radiation Pattern Custom Cuts, allowing to visualize specific cuts of the 3D pattern
Added ability to calculate multiple frequencies in parallel
- This function is currently directly controlled by the user in Simulation Control in Physics
Added new computational algorithm for more accurate simulations, utilizing higher order elements
- This can be controlled in Simulation Control in Physics

Improvements:

Updated Python Plot UI
Added new icons to distinguish Python Plots and ParaView
- Python Plots are now opened with the rightmost icon under the Visualization block, using the Eye symbol
- ParaView can still be opened using the second icon from the right under the Visualization block, using the ParaView three stripe logo
Modifying Geometry Variables in Simulation Control no longer resets the units in FreeCAD CENOS Parameters spreadsheet
Added ability to save a screenshot of 3D results directly from Python Plots

Bugfixes:

Fixed incorrect Directivity and Gain results in multiple port Simultaneous Excitation cases
Fixed the simulation STOP button being missing in Parametric Study cases
Fixed CAD replacement process in the From CAD workflow
Fixed Curvature Safety and Surface Gradient not working in Advanced Meshing Parameters
Fixed an issue where the coaxial port would produce "Null determinant" error when placed on the Z axis
Fixed Single Port cases not generating Extra Results and PDF report when the user had defined Simultaneous Excitation
- Existing cases will generate the PDF report, but Extra Results generation will require a recalculation of the case
Fixed issue where results would not open for cases using Custom application type and a Conductor role
Replaced missing roles in all application types
