Latest Enhancements in XF7
Current Version: Release 7.3.2
This release of XF7 features enhancements for the magnetic resonance (MR) community, plus a few improvements in usability and performance that are beneficial to all users.
New Features in XF7:
MR-related Output Types of MR Transmit Efficiency and Approximate MR Image:
Other Recent Enhancements:
MPI + GPU and Unlimited Memory Support
By combining Message Passing Interface (MPI) technology with XStream GPU Acceleration, multiple high-performance graphical processing units (GPUs) in separate computers can be linked together, resulting in tremendous increases in processing speed and available memory. Complementing this technology with unlimited memory support gives XF7 the robustness to simulate massive problems exceeding billions of cells.
External Queue Integration (EQI)
Many XFdtd users work in computational environments that include one or more high-performance computing (HPC) systems. In this environment, a desktop workstation is used to prepare a Project, create simulations and view results, but the simulations are performed on an HPC system. Such a system typically has an existing job control system installed on it such as the Portable Batch Sytem (PBS), Sun Grid Engine (SGE) or Simple Linux Utility for Resource Management (SLURM). Starting with version 7.3.1, XFdtd includes External Queue Integration (EQI) to allow users to queue simulations directly with such systems instead of manually submitting them for execution or queuing them locally.
STL and DXF Export of Geometry
In addition to the suite of solid model formats, XF7 can now export STL and DXF files. These file formats are used primarily for rapid prototyping and are compatible with many software packages.
Bend Solid Geometry and Project a Sheet
These two new solid modeling operations facilitate the creation of conformal geometry. The bend operation wraps geometry around a cylindrical path and the project a sheet operation embeds faces in another object.
ODB++ designs are now previewed during import. In some scenarios only a portion of the PCB is required for the 3D simulation. During preview of the PCB the user can select to import only the area of interest.
Simulation Creation Optimization
For parameter sweeps where the changes in parameter values do not require re-meshing, simulation creation is now many times faster.
