Clarity 3D Transient Solver

Know the radiated emissions before booking lab time

Clarity 3D Transient Solver calculates the radiated emissions from the complete product — board, cables, and enclosure in a single model. This is the analysis that reveals whether an EMC issue exists while it can still be resolved in the design.

3,600+ installations throughout the Nordics

The challenge

It costs you time and money

  • The EMC issue is only discovered in the test chamber
  • No one knows which part of the product is radiating
  • Every design change requires a new test session
  • Support responses that take days

The solution

We give you control back

  • Radiation calculated across the entire product before it is built
  • The source is located rather than guessed
  • Modifications verified in simulation instead of through a re-test
  • Local hotline with responses from a specialist on the same day

HOW IT WORKS

The complete product in one model

The enclosure is part of the systemRadiated emissions rarely come from the board alone. Cables, enclosure apertures, and surrounding mechanical parts act as antennas, which is why they must be included in the model.
Built for electrically large modelsA complete product is large when measured in wavelengths. The solver is designed to distribute this computation across multiple cores, making the task practically feasible.
Actionable insightsThe result shows not just the emission levels, but where they originate. That is the difference between knowing a design fails and knowing why.

VALUE

Transient Solver covers radiated emissions from the complete system

Board, cables, and enclosure calculated together, enabling EMC verification during the design phase.

What it calculates

EMC is about the complete system, and the system is larger than the PCB.

The model

The model must include both electronics and mechanics; otherwise, the results will not be meaningful.

The results

What an EMC engineer needs is a clear direction, not just a number.

Scaling

Simulating complete systems requires significant compute resources, and the method must keep pace.

Implementation

How Transient Solver works in practice

Cadence delivers the solver. Nordcad helps you apply it before booking physical tests.

Start with a product you have already measured

A product with an existing EMC test report provides the ideal baseline. This allows you to validate the simulation model against real physical measurements before relying on it for design decisions.

Guidance on what to include in the model

Determining which mechanical details matter and where simplifications can be made. These choices ensure the results remain accurate while keeping simulation times practical.

Local expertise and ongoing support

You gain direct access to specialists who understand both electronic design and EMC principles, ready to review and interpret results alongside your team.

A brief conversation is usually enough to determine if simulation can shift your EMC verification earlier in the process. No sales pitch. No pressure. Just a practical discussion about your recent EMC testing experience.

FAQ

Frequently Asked Questions

No. The product still needs to be tested and certified. Simulation changes when you discover whether there is a problem — and makes it possible to verify a solution without booking a new measurement slot in the lab.

That depends on the model. A result built on a well-considered model is accurate enough to identify the source and compare two solutions. That is what enables shifting the work earlier in the process.

Yes, if the question concerns radiation from the product. The enclosure and cables are often what actually radiates, and a model with only the PCB answers a different question.

3D Solver calculates the behavior of structures in the near field — the connector, vias, package. Transient Solver calculates radiation from the entire system in the far field. A product can have fine interconnections and still fail the EMC test.
