WIPL-D, a Serbian developer of commercial electromagnetic (EM) software, has become a key alliance partner and original equipment manufacturer (OEM) supplying its technology for use within the AntSyn antenna synthesis and optimization module from NI AWR.
WIPL-D Pro is an extremely powerful 3D electromagnetic solver that provides fast and accurate analysis of arbitrary metallic and dielectric/magnetic structures. The WIPL-D Pro EM engine is based on the method-of-moments (MoM) surface integral equation (SIE) approach and advanced techniques such as higher-order basis functions and quadrilateral meshing, which produces EM simulations with very high accuracy. These techniques, together with software and hardware accelerations, make the WIPL-D engine extremely fast in solving complex antenna problems.
With WIPL-D Pro, it is possible to create complex 3D models using wires, plates and predefined 3D objects as building blocks. The Preview window gives a deep visual insight into the model. One great feature is access to all the data defining node coordinates, wires, plates and other entities, which gives the user great control over every single detail of the mesh. The objects used are already meshed, and the user can clearly see exactly what goes into the simulation process, with the possibility to influence it by changing the mesh manually.
A powerful numerical engine drives this modeling and simulation tool. Quick and efficient calculations, based on the Method of Moments (MoM) and empowered with quadrilateral mesh and high-order basis functions (HOBFs), yield highly accurate results (distribution of currents over surfaces, near field results, far field pattern and circuit parameters). MoM, quad-mesh and HOBFs significantly decrease required number of unknowns and memory requirements for simulation. Linear systems formed by MoM are solved by direct (in-core or out-of-core) methods. Simulation can be parallelized in many ways (multi-core computers, GPU cards, multiple hard disks for out-of-core solution).
For electrically large structures, special techniques are applied in order to reduce memory requirements and speed-up simulation. Smart reduction option is used for antenna placement setups and can decrease memory requirements up to 10 times. There is also Shadow reduction, which enables the user to explicitly define parts of the model where the order of approximation will be reduced, such as structures below platforms, bottom parts of vehicles and airplanes etc. Starting from version 9.0, WIPL-D Pro has the ability to speed up the calculation time up to 40 times in comparison with previous version thanks to GPU Solver.
