Additionally, improved the efficiency of the overall circuit cross-talk solution by allowing certain phases of a MoM or FDTD cable solution to be skipped in a configuration where only circuit cross-talk is required to be calculated. A speed-up of up to two orders of magnitude can be observed for the cross-talk calculation phase when comparing to Feko 2019.3.2 where cross-talk was calculated on a per frequency basis. Added support for a wideband solution for cross-talk calculations of cable circuits. Decrease the memory footprint for the MLFMM solution phase by using shared memory for matrix by vector multiplication. Both the memory footprint and the computation time for transfer functions are decreased. Improved transfer function computation for MLFMM. The matrix fill times now scale linearly with the number of cores used for the parallel simulation. The non-uniform distribution of elements between boxes could have resulted in a few boxes dominating the solution time and increasing the number of cores would not result in faster solutions. Models with a combination of fine detail and uniform meshes often resulted in some MLFMM boxes with many more elementscompared to other boxes. Substantially improved parallel load balancing for the MLFMM. Added support for parallel simulations with the direct ACA solver on machines with distributed memory architecture (parallel support on multiple nodes). Note: Enable OpenGL rendering for 2D graphs to improve performance when interacting with traces that have a large number of points, in particular those that have many overlapping lines. Improved the implementation of 2D Display OpenGL rendering in POSTFEKO. mov format than before, providing better control over the resulting export by using different combinations of the export size and export quality settings. There is also more variation between the different export quality setting for animations in. The file size of example exports were up to 50 times smaller compared to the previous version using the same export settings. Upgraded the library that is used to export animations. Added support for the new PCB equivalent source that uses PollEx current data. fek file version to 172 to accommodate new features.
Extended the DA card (settings for writing additional data files) with the option to export files for thermal analysis. An equivalent source is defined that uses the current data as impressed line currents. Added the AJ card for importing printed circuit board (PCB) current data from PollEx. Extended CEM validate to issue a warning if the wideband circuit crosstalk method could be utilised for cable harnesses, but there are requests in the model that will trigger a full-wave solution. Extended the Solver settings dialog with an option to export files for thermal analysis when running the Feko solver. Added a PCB equivalent source that uses printed circuit board current data imported from Altair PollEx. The most notable extensions and improvements to Feko are listed by component.
