WIPL-D Pro CAD 2025 (Advanced 3D EM Solver & Pattern Making)

Overview of WIPL-D Pro CAD 2025

WIPL-D Pro CAD 2025 is not merely a CAD interface layered over a solver. It is a unified simulation environment where geometry creation, meshing, solving, and result visualization are tightly integrated. The software is built around WIPL-D Pro, the company’s flagship MoM-based EM solver, which employs higher-order basis functions and a quadrilateral mesh to reduce the number of unknowns while maintaining exceptional accuracy. WIPL-D Pro CAD extends this engine by adding solid-based model creation, import capabilities for major CAD formats, and an automated meshing workflow that prepares geometry for simulation without manual intervention.

The suite is designed for engineers who work with electrically large structures, from single antennas to full platform-level installations. Whether you are analyzing a reflector antenna, simulating antenna placement on an aircraft, or performing EMC/EMI studies, WIPL-D Pro CAD 2025 provides a frequency-domain full-wave solution that balances speed with precision. The software is available for Windows platforms, with a Linux version of the EM kernel available for high-performance computing environments.

Key Features of WIPL-D Pro CAD 2025

The 2025 release offers a comprehensive feature set that addresses the entire simulation workflow. Below are the standout capabilities that define the user experience.

Full-Wave Method of Moments Solver

At the core of WIPL-D Pro CAD 2025 is the Method of Moments (MoM) engine, which solves surface integral equations for arbitrary metallic and dielectric/magnetic structures. By using higher-order basis functions, the solver achieves accurate results with fewer unknowns than conventional low-order methods, making it particularly effective for electrically large problems.

Integrated 3D CAD Modeling

The software includes a native solid modeler that supports primitives, boolean operations, and parameterized geometry. Models can be created from scratch or imported from popular CAD formats including Parasolid, ACIS (SAT), STEP, IGES, CATIA, ProEngineer, Unigraphics, VDA, and STL. The import process includes automated model repair and defeaturing, which simplifies complex assemblies before meshing.

Automatic Quadrilateral Meshing

WIPL-D Pro CAD 2025 features a fast, controllable automatic mesher that generates quadrilateral meshes suitable for the MoM solver. The meshing algorithm is particularly effective for highly curved and small surfaces, and it monitors model changes to prevent unnecessary re-meshing.

GPU-Accelerated Computation

The solver supports GPU acceleration for matrix operations, significantly reducing simulation time for large models. This capability is available alongside multi-threading support, with license configurations scaling up to 16 threads and beyond.

Symbolic Modeling and Parameterization

Users can define symbolic variables and expressions directly within the model, enabling parametric studies and design optimization. The 2025 version extends symbol definition support to 4,096 characters and adds new mathematical functions, hints, and a find-and-replace mechanism.

Cosite Antenna Coupling Analysis

A major addition in 2025 is Cosite analysis, which evaluates coupling between antenna systems on shared platforms. The software automatically creates ellipsoids around areas of interest to reduce unknowns, and it offers both exact and Friis-model solution modes with multiple excitation types.

Advanced Post-Processing with WIPL-G

The new WIPL-G application replaces the older post-processor and provides enhanced visualization and analysis of simulation results. It supports scattered field calculation, near-field and far-field plotting, and fast radiation pattern computation.

What’s New in WIPL-D Pro CAD 2025

The 2025 release introduces a substantial set of enhancements that improve both performance and usability. The most impactful changes are summarized below.

64-Bit Application Architecture

The entire program is now a native 64-bit application. This shift enables smoother preview, saving, and meshing of extremely large models, and it provides more reliable memory management compared to the previous 32-bit version.

Improved Multi-Monitor Support and UI Stability

Working with multiple monitors is now more comfortable, and rendering flicker in the project tree, symbol table, and preview window has been eliminated.

Domain Decomposition Solver Integration

The Domain Decomposition Solver can now be invoked directly from the CAD environment, streamlining the workflow for large and complex simulations.

New Basis Functions and Green Functions

Physical Optics (PO) basis functions are now accessible from CAD, and PEC, PMC, and Half-Space Green Functions have been introduced, expanding the range of solvable problems.

Meshing Improvements

The meshing process has been accelerated, and mesh quality for coaxial ports, waveguide ports, and periodic boundaries has been improved. The mesher now optimizes itself to avoid unnecessary re-meshing when model settings change.

Material Handling Enhancements

Distributed loadings now apply to all metal bodies, and domain assignment can be performed via imaginary permittivity, imaginary permeability, or loss tangent. After Boolean operations, new regions are filled with vacuum rather than PEC, which better reflects physical reality in many scenarios.

How to Use WIPL-D Pro CAD 2025

The typical workflow in WIPL-D Pro CAD 2025 involves four main stages: geometry preparation, meshing, simulation, and result analysis. The following steps provide a practical overview.

Step 1: Create or Import Geometry

Start by launching WIPL-D Pro CAD. You can build models using the built-in solid modeling primitives, or import geometry from a CAD file in formats such as STEP, IGES, or Parasolid. The software’s automatic repair tools help clean up imported models before meshing.

Step 2: Assign Materials and Excitations

Use the symbol table and material library to define the properties of your structure. WIPL-D includes a library of over 80 predefined materials, and you can define custom materials using permittivity, permeability, or loss tangent values. Apply excitations such as generator/port, field generator, or current generator depending on your simulation type.

Step 3: Generate the Mesh

Invoke the automatic mesher to create a quadrilateral mesh suitable for the MoM solver. The mesher provides a few control parameters, making it accessible even for users who are new to EM simulation. For large models, the mesher operates quickly and avoids redundant re-meshing.

Step 4: Run the Simulation

Configure solver settings, including frequency range, basis functions, and whether to use the Domain Decomposition Solver. GPU acceleration can be enabled for faster matrix operations. Once configured, launch the solver and monitor progress through the CAD interface.

Step 5: Analyze Results with WIPL-G

After the simulation completes, open WIPL-G to visualize results. You can plot radiation patterns, near fields, scattered fields, and S-parameters. The post-processor supports export of data for further analysis in external tools.
