Outputs will be different cross-section planes to Gwyddion file and a text file (from single point). Calculation will be performed on CPU or on GPU and material mode selection for speedup will be tested. text/html 2025-02-19T10:27:49+00:00 Anonymous (anonymous@undisclosed.example.com) http://gsvit.net/wiki/doku.php?id=start:getting_started&rev=1739957269&do=diff Getting started Even if we try to make GSvit as much user friendly as possible, it is still far from ideal state. Therefore, after Download and installation we recommend trying some of the provided examples, like that shown in Your first simulation page. There are also some Application examples to show GSvit use for some real world calculations, these are however limited by our area of interest and GSvit, as any other FDTD package, is in principle applicable also in many other fields. text/html 2025-02-19T10:27:49+00:00 Anonymous (anonymous@undisclosed.example.com) http://gsvit.net/wiki/doku.php?id=start:gsvit_vs._xsvit&rev=1739957269&do=diff GSvit and XSvit Originally, only a command line solver GSvit was released. Benefits of a command line tool are namely seen when you want to do some scripting, or you are using remote access to some high performance computing system. To use GSvit via command line, typically a parameter file is set up in a text editor (or e.g. via some script) and then it is passed as an argument to GSvit solver. So this is how typically invoking GSvit looks like: text/html 2025-02-19T10:27:49+00:00 Anonymous (anonymous@undisclosed.example.com) http://gsvit.net/wiki/doku.php?id=start:installation&rev=1739957269&do=diff Download and installation Download GSvit can be downloaded as stable version, which is recommended, either as a Windows binary installer or as source code. A current development version can be also obtained from Subversion repository, however this is not recommended as code under development might behave unexpectedly. text/html 2025-02-19T10:27:49+00:00 Anonymous (anonymous@undisclosed.example.com) http://gsvit.net/wiki/doku.php?id=start:tests&rev=1739957269&do=diff Automated tests If GSvit is started with “test” as an argument, followed by test number, it can run an automated test. For key tests even a precomputed value is installed, so result can be compared to it automatically. If a GPU is present in the computer and GSvit is translated with GPU support, it is recognized, reported and used for comparison to CPU. text/html 2025-02-19T10:27:49+00:00 Anonymous (anonymous@undisclosed.example.com) http://gsvit.net/wiki/doku.php?id=start:using_xsvit&rev=1739957269&do=diff Using XSvit XSvit is a graphical interface for command line solver GSvit. It serves as an editor of parameter files, where both parameters editing graphical user interface and direct editing of the parameter file are supported. XSvit can be used for creating or altering the parameter files, running the computational solver (GSvit) and running Gwyddion which serves as viewer of most of the results.
