Menus¶
Menu “File”¶
- “New project”
Create a new project (empty project)
- “Open project”
Open an existing project with the I-Simpa file format
*.proj
- “Import new scene”
Import a new 3D geometry in the existing project. Some Import options are available at this step.
Import file formats:
Astuce
When you import a new scene, except the geometry, all previous data (sources, receivers, materials…) of the current project are unchanged. You can use this option if you want to keep all current data, and just import a new geometry. If you want to remove all data, you need to create a new project.
Note
Numerical codes within I-Simpa (like SPPS) are very sensitive to the quality of the import geometry. Although I-Simpa can correct some defaults during importation of a geometry, it is recommended to pay a particular attention to the creation of the geometry. Read the recommandations here.
- “Export scene”
Export the current 3D geometry from the current project (without additional data)
Export file formats:
- “New scene”
This option able to create a parallelepipedic scene. This is the simple way to create a 3D scene with I-Simpa. This can be useful for starting with I-Simpa. For more realistic scenes, users have to build 3D scenes using a CAD software, and then, importing the geometry using one the possible import file format (see “Import new scene” in the file menu).
Note
Using the built-in option for creating a rectangular geometry, each main face of the geometry (i.e. there are 6 main faces), is split into 2 triangular face elements. This mean that, when defining the acoustical material for each face, you will only have the possibility to affect two different materials for each main face (one on each triangular face). Most of times, users will consider a single material for each group.

Note
I-Simpa must be restarted in order to apply the selected language.
- “Change application data folder”
Allows to change the default folder for the Application Data
- “Exit”
Exit I-Simpa.
Note
When starting I-Simpa, the last project (if available) will be automatically loaded.
Menu “Edition”¶
Avertissement
The “Undo” and “Redo” options acts only on action realized in the three “Project”. By activating the “Undo” and “Redo” options, I-Simpa can be slowed down. Since, these options are not essential, it is recommended to disable these options (see the “Settings” of I-Simpa).
- “Undo”
Cancel the last actions (recursive option).
- “Redo”
Restore the last cancellation with “Undo”.
Menu “Simulation”¶
- ‘Play’
Play an animation within I-Simpa (see also Toolbar ‘Animation’). This is functional only if compatible data have been loaded.
- ‘Pause’
Pause an animation within I-Simpa (see also Toolbar ‘Animation’). This is functional only if compatible data have been loaded.
- ‘Stop’
Stop an animation within I-Simpa (see also Toolbar ‘Animation’). This is functional only if compatible data have been loaded.
- ‘Meshing’
Generate a meshing within I-Simpa using the mesh generator TetGen.
Note
This option is functional only if the 3D geometry is compatible (see Import options).
Menu “View”¶
This menu proposes several display modes for the 3D view of the geometry.
‘Face’¶
- ‘Oustide’
Show faces oriented outside the geometry. If all faces are well oriented, only the exterior of the geometry should be visible.
- ‘Inside’
Show faces oriented inside the geometry. If all faces are well oriented, only the interior of the geometry should be visible.
- ‘None’
Hide all faces.
‘Material color’¶
- ‘Original’
Show faces with their original color/texture (i.e. following the CAD exportation)
- ‘Material’
Show faces with color associated with materials (i.e. following I-Simpa material assignation).
‘Lines’¶
- ‘All’
All lines are visible.
- ‘Contour’
Show lines around co-planar surfaces (co-planar faces are merged, only for the display).
- ‘None’
Hide all lines.
‘Hide meshing’¶
If a mesh has been generated, this option allows to hide the mesh representation in the 3D view.
‘Reinitialize camera’¶
Return to the default 3D view.
‘Camera’¶
Change the camera mode (use the mouse and/or the arrow keys to change the view.
- ‘First person’ mode: Users visualize the 3D scene with its own eyes:
Left clic + motion (left, right, up, down) ≡ head motion (left, right, up, down)
Right clic + motion (left, right) ≡ head motion (left, right)
Right clic + motion (up, down) ≡ zoom + and zoom -
- ‘Rotation/Zoom’ mode:
Left clic + motion (up, down) ≡ zoom + and zoom -
Left clic + motion (left, right) ≡ zoom + and zoom -
Right clic + motion (left, right, up, down) ≡ rotation (left, right, up, down)
Center clic: move scene
