June 18, 2024: The content below helps navigate the new features in this release. A full list of updates is available in the Reference Manual's Appendix.
XF 7.11.0 upgrades several third-party libraries, adding support for Linux RHEL8 and dropping support for RHEL6, and requiring CUDA 11.4 for use with GPU acceleration. XF 7.11.0 upgrades FLEXlm licensing libraries to version v11.19.1-TRL from v11.16.2-TRL. Customers using a floating license must update their floating license server.
Additional Capabilities
This version introduces over 50 usability, performance, scripting, and other updates.
Here is a select list of modifications:
- AC Circuit solver uses direct solver which is faster and more resilient for linear simulations. Option available to revert to iterative solver.
- Schematic has on screen display for hotkeys.
- Added support for high DPI displays. In doing so the cleanlooks and plastique themes were removed. They are available via command line option if necessary.
- Significantly improved load time of circuit superposition results.
- Updated CAD import to support PTC Creo 9 files.
- Added project specific settings for EQI.
- Graph regions can be copied and pasted between graphs.
- Added option to keep color when replacing materials.
- Default 3D mesh setting changed to 3D-off to allow setting of bounds prior to display.
- CEO simulation summary tab now uses correct preference units.
- CEO goal window now remembers location.
- Fix layout of tuner tables in CEO.
- Preference added not to show band text on XY Graphs.
- User settable font size and color in script editor.
- Linear unit now used for axial ratio.
- Reintroduced the option to save data for far zone post-processing option to reduce data and runtime.
- Now can specify bitrate when exporting movies of fields.
- Port name now added to misc info of more FDTD results.
- UAN export now explicitly only available for gain results.
- Removing wrapping of FDTD engine output text in simulation output tab.
- Changed S-Parameter notation so that the schematic matches the project results.
- Schematic analysis workbench now copies line styles to the tuned one from the originals.
- Dispersive material calculator, libraries name column, PCB import window now remembers size.
- Mesh operations are now invalidated instead of removed when a constitute part is deleted.
- Now only physical MAC ids are reported for licensing usage on Windows.
- Improved consistency of Y-Axis and graph titles between FDTD and schematic results.
- Fix text tooltip for execution tools in scripting window.
- Now repositions workspace windows on screen when opened if they wouldn’t have been visible.
- Added right click menu option to assign circuit component definition.
- Prevents materials not found in the mesh from being shown in the system sensor’s result table for dissipated power per-material results.
- Added API to get schematic’s result selection.
- Fix to exportRotatedGainAndPhaseToUANFile for superposition results.
- Fixed a bug where running a simulation with a TFSF planewave excitation with XStream will typically introduce an incorrect time delay (positive OR negative) to the excitation, causing time domain results to be shifted in time, and frequency domain results to be shifted in phase. This issue only occurred when the planewave propagation direction is not perpendicular to the X-axis.
- Fixes a bug where xfsolver may crash or give incorrect results if more than 201 electric materials are defined.
- Fix to launching RDQS.
- Fixed naming convention for XF Block results in the schematic.
- Fixed to terminal renderings when tightly zoomed.
- Fix to dielectric volume averaging in waveguide at boundary of simulation space.
- Fix for loft smoothness sliders sometimes not having an effect.
- Fix to shear notation.
- Improvement of dielectric volume averaging and XACT part intersection representation.
- Fix of loft between parts with different parent assembly orientations.
- Superposition simulations can be used with Huygens sensors.
- Added missing scripting documentation in ResultQuery.
- Fixed Huygens export when waveguides are used.
- Components no longer rendered when mesh rendering set as 3D-Off.
- Prevents simulation creation when more materials are in use than are supported by xfsolver.
- Fix selecting center of face in circular pattern.
- Fixes a case where some material not present in the mesh are written into the xfsolver input files, possibly causing the number of materials to exceed the upper limit on number of materials.
- A Schematic’s disabled operating modes are no longer give as options when creating an Apply Circuit Simulation. Likewise, ’Push Schematic to Circuit Post-processing Simulation” now requires that all required operating modes in the Schematic be enabled.
- Fixes a bug where an expression or parameter dependent on another parameter with a value nan, inf, or -inf may give an unexpected result.
