tpt-electromagnetics

Computational electromagnetics for the TPT Solutions ecosystem: MNA circuit simulation, compact semiconductor device models, quasi-static Maxwell FEM, multi-conductor transmission lines, S-parameter network analysis, and power system analysis — built on the tpt-math-*, tpt-fem-*, and tpt-io-* sibling crates.

This workspace is consumed as path dependencies within (and across) the tpt-solutions workspaces. Crates.io publishing is out of scope for the current pass. Every crate is dual-licensed MIT OR Apache-2.0.

Building

cargo build --workspace --all-features
cargo test  --workspace --all-features

tpt-em-core is no_std-capable (with the alloc feature) and builds for wasm32-unknown-unknown.
