inventsim
High-performance 3D FEM electromagnetic simulation software for engineers designing antennas, filters, waveguides and passive RF components
Accelerate innovation with fast, accurate, and affordable 3D electromagnetic simulation
InventSim Community Edition is now available for free!
Experience our powerful electromagnetic field simulation software — now accessible to everyone for personal, academic, and commercial use. The Community Edition has some feature limitations compared to the Standard Edition.
InventSim is an integrated 3D electromagnetic simulation and optimization platform for RF, microwave, millimeter-wave, and sub-THz component design. Simulate antennas, filters, waveguides, couplers, and other passive devices with the accuracy of the finite element method (FEM) while significantly reducing simulation time.
Powered by a high-performance multithreaded FEM solver with higher-order curvilinear elements, InventSim delivers reliable results for even the most challenging electromagnetic structures. Its intuitive 3D modeling environment, built-in optimization tools, and support for task automation via COM interface help engineers move from concept to validated design more efficiently.
Whether you’re developing next-generation wireless systems, conducting academic research, or teaching electromagnetic design, InventSim provides professional-grade simulation capabilities in an accessible and cost-effective software package.
