QuickWave 2021
Software for electromagnetic design and simulations based on conformal FDTD method.
Dear QuickWave Users,

QWED has continued efforts on extending availability, speed and functionality of the QuickWave software for electromagnetic design as well as the scope of its applications.

We are pleased to announce that the newest QuickWave 2021 has been released.

Since early 2000s, Microwave Heating Module (QW-BHM) has been a breakthrough module of QuickWave 3D software, as it extends the original electromagnetic simulator to multiphysics functionalities, relevant to the thermodynamic effects induced by the dissipation of electromagnetic energy in materials (and subsequently, also those thermodynamic effects alone). Besides heat generation and temperature rise, QW-BHM allows for the modelling of heat flow (subject to various thermal boundary conditions, via its internal QW-HFM module), load movement during the heating (rotation and arbitrary translation), fluid flow (via CFD Fluid Flow Module), and most importantly – nonlinearities in all of the above coupled processes, arising from material parameter changes as a function of accumulated energy or temperature, separately at each point of the computational scenario.
Up to version 2020, the QW-BHM functionalities have been available for 3D projects. Although 3D scenarios are most general and capable of representing any physical geometries, many practical research and engineering problems are axially symmetrical, or sufficiently accurately represented by their BOR (Bodies-of-Revolution) models. QuickWave’s electromagnetic (BOR or vector) solver, QuickWave V2D takes the axial symmetry into account, reducing a 3D (volumetric) simulation by a 2D one, in the long-section of the scenario. This leads to several orders of magnitude improvement in the simulation efficiency and computer memory requirements.

In QuickWave version 2021, BOR/V2D solvers have also been provided for multiphysics problems, and similar improvements in computational efficiency are observed as for the electromagnetic ones. The BOR/V2D representation is directly applicable to two classes of multiphysic scenarios:

Microwave power applicators feeding axially symmetrical tunnels, through which the load is passing. One example are free-fall tunnels and axisymmetrical cavities (S.Bradshaw et al, J.Microwave Power & Electromagnetic Energy, vol.40, No.4, 2007).


Cylindrical batteries, from those most popular in consumer use today up to Tesla’s new Model’3. The modelling of batteries is currently of top interest to industry and research worldwide, due to the need for reducing CO emission, as represented by the European Green Deal Action. QWED contributions here are through the H2020 NanoBat project, where so-called Half-Cell and Full-Cell axisymmetrical battery models (https://nanobat.eu/collaboration/oie) are considered as representative of the above needs.

Automatisation and major accuracy enhancements has been introduced for simulating high-Q resonators - including resonator-test-fixtures for high-precision material measurements for 5G and emerging technologies.

Automatisation and major accuracy enhancements has been introduced for simulating narrow-band and multi-band filters - including  those used in 5G, satellite, and emerging technologies.

New QW-Modeller for QuickWave allows for parametrisation of the model with user defined variables and Spreadsheet workbench for more complex formulas. The parametrisation also allows for optimisation or grid-search procedures of QW-Optimiser Plus.
