Users can now connect to the Ansys License Manager when using an Enterprise license or continue to use their existing Business licenses on the Lumerical license server.<\/p>\n<h2>New Versioning Scheme<\/h2>\n<p>From the 2020 R2 release, Ansys-Lumerical products have adopted the versioning scheme used by all Ansys tools. Since this is the second major release for the 2020 calendar year, it has been labeled as 2020 R2.<\/p>\n<h2>Safe mode in scripts<\/h2>\n<p>The new \u201csafe mode\u201d provides users with enhanced security against malicious scripts. The safe mode is turned on by default in all Ansys-Lumerical products and prevents attackers from accessing or modifying system files. To learn more about the new safe mode check out this\u00a0<a href=\"https:\/\/support.lumerical.com\/hc\/en-us\/articles\/360044709054-Running-script-in-safe-mode\" rel=\"nofollow\">KB page\u00a026<\/a>.<\/p>\n<h2>Options for MPI and firewall exceptions<\/h2>\n<p>The Windows installer of the 2020 R2 release allows users to choose which MPI package they want to install and what firewall exceptions to apply. The default will install the MS-MPI package and apply no firewall exceptions.<\/p>\n<h2>Performance improvements in meshing and gradient calculator for PID<\/h2>\n<p>Finite difference meshing with 2020 R2 makes more efficient use of your CPU, with better thread support and performance improvements. Users can expect modest speedup when using conformal meshing in the CAD, or in engines with multiple threads, especially for projects with complicated geometries. Users of photonic inverse design that choose to calculate the gradient with the precise volume average meshing technique will see substantial speedup and improved accuracy.<\/p>\n<h2>Support for macOS version 10.15<\/h2>\n<p>The 2020 R2 release of Ansys-Lumerical tools now support the latest macOS version 10.15.
