    Designer v0.7.0

  • Checks that explain themselves

    Click a warning to see what was found, why it matters and how to fix it.

    Designer v0.7.0

  • Ports that find their ground

    Add port here says what the port connects to and offers the other metals it found.

    Designer v0.7.0

  • Import VBA macro

    A CST-compatible VBA macro or history list becomes a design, manual mesh lines included, with a report of what was skipped or changed.

  • Sweeps and optimizer

    Sweep one or two parameters, or let the optimizer tune them towards your goals.

    Simulation v0.7.0

  • Metal GPU engine

    The optional Metal engine reduced solver time in the documented benchmarks; agreement depends on the model and stopping settings.

    Simulation v0.7.0

  • CUDA GPU engine

    Optional CUDA builds support NVIDIA GPUs under Windows; solver times depend on the model and runtime.

    Simulation v0.7.0

  • Thin copper as sheets

    Realistic 35 µm PCB copper is simulated as sheets, so runs keep a practical time step.

    Simulation v0.7.0

  • Convergence checks

    Preflight checks block known invalid setups and flag some convergence risks; check convergence after the run.

    Simulation v0.7.0

  • Thin copper in exported models

    A design exported to Python builds the same copper sheets as the designer's own run.

    Simulation v0.7.0

  • Auto mesh mode

    The mesh settings are picked for each design, and any field can be overridden.

    Simulation v0.7.0

  • Parameter sweeps

    Sequences over up to six parameters each, checked before they run, queued, and compared run by run.

    Simulation v0.7.0

  • A stronger optimizer

    Live progress, the best result kept, any number of parameters, and Bayesian, CMA-ES, particle-swarm, genetic and trust-region searches.

    Simulation v0.7.0

  • No run without a port

    A design with no port, or no excited port, is refused with a check instead of failing.

    Simulation v0.7.0

  • Examples keep their mesh

    Supported example-to-design conversions preserve recorded mesh lines. Review conversion limits and compare a new run before relying on equivalence.

    Simulation v0.7.0

  • Optimizer skips misplaced metal

    Candidates the design checks refuse are skipped without a simulation and shown as Skipped.

    Simulation v0.7.0

  • GPU build by default

    A compatible GPU runtime is preferred when the GPU startup preference is enabled; the CPU engine remains available.

    Simulation v0.7.0

  • Mesh convergence

    Refine the automatic mesh until the comparison meets tolerances or reaches the run limit; the study may report Not converged.

    Simulation v0.7.0

  • Run-quality warnings

    A run that did not converge, or whose numbers look suspicious, is flagged in the tree and on its results.

    Simulation v0.7.0
