open source FDTD solver with GPU support
As shown on First simulation page, there are three steps in a succesfull calculation. First step is to setup model that we want to use for the calculation. In brief this means to address the following questions:
All this can be setup via a parameter file, editable in a text editor or using XSvit parameter file viewer. It is described in next paragraphs of this section.
After this is done, we run the calculation, which means that we run the solver GSvit with parameter file as an argument, either manually or from XSvit GUI. We wait until computation is finished, which might take something between seconds and hours, depending on computational domain size, number of steps and complexity of algorithms used.
Finally, we want to analyse results. Text outputs can be analysed in your favourite graph plotting or spreadsheet aplication, cross-section outputs can be analysed using Gwyddion and volume outputs can be analysed by Paraview.
