Remcom announces a major upgrade to XFdtd® Release 7 (XF7), with several new features and enhancements. This point release, which updates XFdtd to Release 7.1, introduces XACT Accurate Cell Technology, a sophisticated meshing and computation method that produces faster, more accurate results when modeling complex shapes.

XACT resolves extremely intricate designs with fewer computational resources. Benefits include faster run times and the power to simulate very complicated geometries. Important geometric features, including complex curved surfaces and small gaps, are resolved using an advanced sub-cellular conformal method. By representing input geometry more precisely, XACT reduces computing resources while maintaining the accuracy of a full wave solver.

Scott Langdon, Product Manager for XFdtd, said, “While sub-cell techniques are not new, XACT builds on existing technology to provide a unified technique for representing thin and/or curved shapes within a cell while retaining XFdtd’s unique capability of making the real mesh visible to the user.”

Another enhancement in the XF7 upgrade is the XTend Script Library. The scripting capabilities of XF7 add control and customization to workflow, allowing users to adapt the software to their unique processes and extend the functionality of the tool. In addition to XTend’s pre-loaded scripts, users may further customize and automate processes as they wish.

XF7 is available in both Pro and Bio-Pro versions. Both include XStream GPU acceleration, 32- or 64-bit analysis module, geometric modeler and postprocessor, shared memory multiprocessor (MPM) at eight cores, and comprehensive variety of 3D CAD import modules. The Bio-Pro version also includes SAR capability and hi-fidelity human body meshes.
