File Menu
The File menu contains options to control creating, opening, closing, and saving RSim files and simulation directories.
Fig. 12 File Menu
New
File –> New has two options:
- From Example
- Simulation
Open Simulation
To open a directory where existing simulation files reside, select Open Simulation from the File menu.
Fig. 13 Open selection from File menu
The default directory, simulations, is created for you when installed RSim.
You can modify this in
the Tools –> Settings –> Host settings –> Paths menu.

Save Simulation
After a simulation is open, going to File –> Save Simulation allows you to save any modifications to the input file. The saving process will also run the translator to create a valid .pre file based on the selected simulation model.
Save Simulation As
After a simulation is open, clicking on File –> Save Simulation As allows you to save any modifications to the input file and write it in to a new file. The saving process will also run the translator to create a valid .pre file based on the selected simulation model.
Close Simulation
After a simulation is open, File –> Close Simulation allows you to close the current simulation and will return you to the Welcome window.
Open Auxiliary File
This can be used to open any file related to a simulation. It is most useful for opening and viewing tally data.
Save Auxiliary File
This can be used to save any changes made to an auxiliary file.
Close Auxiliary File
This can be used to close an associated auxiliary file that was previously opened.
Import
RSim can be used to import several types of geometry files for use either in an RSim simulation, or to be exported for use with another radiation transport code.
The supported import file formats are any of .ele/.node (Tetrahedral Mesh for PHITS), .stl, .ply, .vtk, .h5m (DAGMC), .stp, .step, .p12, .gdml (Tessellated)
Once a file has been imported it can be assigned a material and color like any other geometry.
Export
RSim can be used to export geometries into several file formats. These are .ele/.node (Tetrahedral Mesh for PHITS), .stl, .ply, .vtk, .h5m (DAGMC), .gdml (CSG or tessellated, .vsh5, .tvsh5
Only the geometries that are currently being visualized in 3D View will be included in a geometry export.
Once the geometry has been exported it can be used in other radiation transport codes, such as PHITS, MCNP or DAGMC.
Note
If exporting into a Tetrahedral Mesh for PHITS each part will have an individual .ele/.node file pair. Each file will assume a Universe = 1000. If exporting into a mesh, it is recommended for a minimum tessellation of 0.1, as otherwise it can take a significant amount of time to generate the mesh.
Recent Simulations
To access data to visualize from a recently conducted simulation, select Recent Simulations from the File menu in the menu bar.

Click on the name of the simulation whose data you want to open.
Quit
File –> Quit will close RSim.
