OmniSim is a design environment for the layout and design of integrated optics components bringing truly direction-agnostic capability to the field. It is supports our Finite-Difference Time-Domain (FDTD) and Finite Element Frequency Domain (FEFD) simulators. OmniSim is available as a native 32-bit and 64-bit application. The 64-bit version of OmniSim allows you to include large amounts of memory in your FEFD and FDTD calculations. In combination with the SMP capability (symmetric multi-processing) of the FDTD engine, this enables OmniSim to simulate large devices at very high speed! OmniSim includes a layout editor bringing new levels of usability plus state-of-the-art Finite-Difference Time-Domain (FDTD) and Finite Element Frequency Domain (FEFD) simulation engines, and automatic optimisation to accelerate your design process with Kallistos. The combination of the FEFD Engine and Kallistos permits World leading automatic optimisation speeds. Allows you to design epitaxially grown structures as easily as periodic arrangements of nano-particles thanks to its mask layer editor and its 2D and 3D shape library. Advanced 2D and 3D FDTD Engine, supporting multi-core and clustered calculations. Extremely fast multi-core 2D finite element frequency domain modulator.
