WIPL-D Pro 7.0

Features introduced in version 7.0:

• Multilevel fast multipole method greatly extends the maximum solvable electrical size (more details...)

• Parametric sweep analysis - all simulation results can be analyzed with regard to a project symbol

• Fast graphics in Preview window easily handles complex 3D models containing large numbers of plates

• Fast open and save operation for projects containing large numbers of plates

• Fast visualization of all results containing a large amount of data (e.g., electric and magnetic currents over a 3D model)

• Support for optimization of models created in AW Modeler

• Custom shaped reflector using generatrix specified within the user defined data file

• Zoom Area option in 2D and 3D graphs

• Optional saving of settings in Graph window (.e.g., preserving range settings when displaying radiation pattern for different frequencies)

• "Save as With Results" option

• Permanent and time-limited network license supported

• Index is added to User's Manual

Improvements of old features

• Out-of-core now supports the distributed loadings option

• Visualization of currents over wires is completed (e.g., presentation of currents over helix object and virtual wire objects is enabled)

• Export to Touchstone format enabled for formats AD2 (de-embedded s-parameters) and AD3 (s-parameters for reference impedance other than 50 ohms) in addition to format AD1

• Symbols are now accepted in multi-band part of the Frequency dialog box and in the Waves table

• The Show window displays node coordinates in active project units, instead in meters

• After selecting domains (Alt+D) / layers (Alt+L) for display the model preview is preserved after creation of a new entity

• Deletion of wires causes deletion of all corresponding generators / junctions

• Placement of generator at arbitrary elements of an array obtained by Copy manipulation

Features introduced in version 6.4:

• Three to four times faster incore/outcore matrix inversion on single core CPUs (see the new speed benchmark)

• Multithreading: Matrix inversion speed-up on multicore CPU computers

• Simulation of EM fields coupled through apertures in infinite PEC/PMC planes

• Adaptive domain-wavelength related meshing lowers number of unknowns for multi-domain problems

• Multiple frequency band simulation and optimization

• Enhanced results visualization: Graph markers with search function

• Link to AW Modeler and Time Domain Solver

Features introduced in version 6.1:

• Fast iterative solution of large scatterers and antenna placement structures - The new set of basis functions enables very fast, accurate, iterative solution of large linear systems in case of electrically large scatterers and most antenna placement structures.

• Fast and memory efficient simulation of antennas on large platforms - Smart reduction of expansion order enables solution of antenna placement structures with up to 10 times less memory with preserved good accuracy.

• Improved accuracy of integration - Accuracy automatically provided by the software is enhanced, thus requiring less intervention by the user.

Applications of these new features

Features introduced in version 6.0:

• Outcore solver - Structures requiring more than 15,000 unknowns can be simulated using the hard drive as storage space during the computations. Thanks to efficient communication with the hard drive, this is done in a reasonable amount of time, even for very large number of unknowns.

• High efficiency and accuracy in modeling large reflector antennas (advanced meshing of Reflector object halves the number of unknowns).

• New tabular listing of output results (adjustable number of significant digits, listing of arbitrarily large files, halved hard drive space consumption, easy copying to Excel tables).

• Project names longer than 8 characters supported.

• Optimization of circuit parameters obtained by de-embedding.

• Optimized automatic edging.

• Open and Save As dialog boxes fully compatible with newest Windows OS.

• Alternative de-embedding procedure offering better accuracy in most cases.

• Easy zoom in, zoom out and move of the model preview by using mouse wheel.

• Automatic Intersection of overlapping Pattern entities, used for creation of multilayered structures.

• Presentation of single data point in Smith Chart.

• Customized Legend - position, transparency, and framing can be specified.

• Easy creation and usage of Notes, Header, and Footer.

• Logarithmic scale for frequency axis in 2D graphs.

• New toolbars for quick plotting of results.

• Copying of Grids.

Corrected bugs:

• Corrected listing of near field results.

• Wire-only structures are shown in Radiation and Near Field 3D graphs.

• Usage of symbols enabled in the Helix object.

• Non-standard fonts used for listing and plotting are replaced with standard system fonts. This eliminates problems that some users had with installation of non-standard fonts.

• Improved plotting of currents over the structure: corrected plotting of current over plates with highly obtuse angles, automatic specification of number of current calculation points for wires.
