June 8, 2021: The content below helps navigate the features in this release. A full list of updates is available in the Reference Manual's Appendix.
Transient EM/Circuit Co-Simulation
XF's co-simulation capability supports nonlinear components, such as TVS diodes. The netlist component definition allows users to import a text file and define SPICE models containing diodes. Using transient co-simulation, the circuit solver and FDTD solver simultaneously simulate the SPICE model and full-wave 3-D simulation space, respectively.
Additionally, an XF macro is provided that facilitates the import of a netlist library as separate netlist component definitions.
Optenni Lab Integration
This release builds on existing XF-Optenni Lab integration by adding support for parameter sweeps. After performing a parametric analysis in XF, users can export simulation data for each value of a parameter sweep to Optenni Lab for analysis.
This integration also supports post-processing on both Windows and Linux.
Select Mesh Cutplane
Functionality added to the mesh view controls allows users to specify 2-D mesh cutplane locations with the mouse by clicking in the geometry window. A toggle button added to each x, y, and z slice locates the 2-D cutplane in its respective direction, assisting in mesh visualization prior to simulation.
