| - | To start playing with Xraytrace you can use some of the examples shown on these pages. | + | Xraytrace is run from console, using a parameter file as argument. Parameter file is a plain text file with some commands (described in the other sections of this documentation) and with links to other files. |

| + | |||
| + | A very minimum set needed for a reasonable calculation is shown here. It consist of three files: parameter file, sample geometry definition file and table of material parameters. You can paste the content below to newly created files or you can {{samples:getting_started.tar.gz|download them}}. | ||

| + | Now, run the solver from command line with test.par as an argument. | ||
| + | After a while, you should get the results. Open the file out.vtk in [[http://paraview.org|Paraview]] | ||
| + | and you should see something like this: | ||
| + | |||
| + | |||
| + | {{ :started.png?400 |}} | ||
| + | |||
| + | This is nearly all what we can expect - at least for the basic calculation. We get the standing wave distribution within the object and we get a sum of the electric field intensity in each material. Running this for different wavelengths gives us similar information like the experiments. | ||
