Installation Requirements 2. Supported OS 3. List of Main Bugs Fixed Since Last Release 4. Known Issues -------------------------------------------------------------------- -------------------------------------------------------------------- 1. Installation Requirements -------------------------------------------------------------------- - Administrator rights are required during the installation process. - NVIDIA graphics card, with support for OpenGL versions higher than v3.0. -------------------------------------------------------------------- 2. Supported OS -------------------------------------------------------------------- - Windows Server 2012 R2 - Windows 7 64 bit - Windows 8 64 bit - Windows 8.1 64 bit - Windows 10 64 bit SEMCAD X Matterhorn V18.2.2 uses Acceleware's Tauranga library version 11.1.13. Please get the latest NVIDIA driver for your hardware from the Acceleware website: https://acceleware.com/fdtd-11.1.13. Please note that only NVIDIA GPUs with CUDA Compute Capability 1.3 or higher are supported by the Sim4Life CUDA solver (e.g., Tesla C10XX). The AXE solver supports only CUDA Compute Capability >= 2.0. -------------------------------------------------------------------- 3. List of Main Bugs Fixed Since V18.2.1 Release -------------------------------------------------------------------- - Case 129074: Significant accuracy improvement in Vector Potential reconstruction, in particular for coarse grid resolutions - Case 125192: Fix of a bug which was causing the model of a different new project to disappear when clipping the previous model in a slice field viewer and saving the project - Case 125090: Fix a bug in EM LF Clone As function which was producing additional overall field sensor and Air material setting - Case 124666: Fix in Python API to display correct version number when running s4l_v1.api.application.run_application() - Case 111573: Fix of a bug in unstructured LF solver that adding a 180deg phase to current source has no effect -------------------------------------------------------------------- 4. Known Issues -------------------------------------------------------------------- - Case 32807: Instability for some rare dispersive material configurations - Case 40481: Python memory usage occasionally still occupied after resetting analysis - Case 47035: Random problems in visualization of Dispersive Viewer - Case 54000: Random element appearing in Gridder - Case 61881: Rare issue with distribution of the simulation job to the GPUs when using CUDA - Case 86865: Job priorities may not correspond to the job execution - Case 90292: Under-performance of CUDA solver compared to Sim4Life V3.4 - Case 98764: Potentially decreased accuracy in rare specific events for sensor combiner of Far-field sensor - Case 124573: Streamline viewer occasionally showing artifacts near sources
