The software employs a "correct-by-construction" methodology. Students can draw a schematic using lumped components (resistors, capacitors, inductors) and transmission lines. The software can then automatically generate the physical layout for fabrication, or conversely, extract circuit models from physical layouts.
To illustrate the value of even the old Ansoft Designer Student Version, let's walk through a classic junior-year lab project. ansoft designer student version
The serves as a vital foundation for engineering students and hobbyists entering the field of radio frequency (RF), microwave, and high-frequency circuit design. Developed originally by Ansoft Corporation before its acquisition by Ansys, this platform delivers commercial-grade simulation capabilities in a free, accessible format. Today, its core technologies live on within the Ansys Electronics Desktop Student bundle, which combines classic circuit design with advanced electromagnetic (EM) solvers like HFSS.

Despite the coarse mesh, the student version returns results within 10-15% of measured values—excellent for an undergraduate lab.
If you want to learn electromagnetic simulation from first principles, OpenEMS uses the Finite-Difference Time-Domain (FDTD) method. It is more powerful than Ansoft Designer’s MoM but has a steeper learning curve (requires MATLAB or Python scripting).
That limit taught a deeper lesson: design efficiently. Don’t waste nodes. Simplify. That’s engineering.
