Additional Components
Coupling Options RecurDyn Coupling

Select the checkbox to view the Import Geometry from RecurDyn option after you right-click Geometries in the Creator Tree. This allows you to read a *.wall file generated by RecurDyn after which you can import a Geometry from RecurDyn.

Once the Geometry is imported and the coupling interface is enabled, RecurDyn can control the Geometry motion. The forces experienced by these Geometries are passed back to RecurDyn, which then calculates any motions resulting from these forces.

Enable FlexTire

Select the checkbox to display the FlexTire options in the Geometry section. This functionality requires an additional license as it is a product developed by one of Altair's partners. For more information, contact your Altair Sales representative.

Solver Options Solver Options

Select the Experimental Contact Models checkbox to show the experimental models in the Physics section. These models have been built into the software, but are not considered to be widely suitable for industrial applications. It is recommended to exercise caution when using these models.

Data Browser
Color Options Select the Text, Link, and Background colors to configure the color of the data browser text and background.
Display Options
Default View Projection options Perspective

Select this option to change the default 3D view to use the perspective projection automatically. The option to change the view to orthographic is available in the View toolbar.

Orthographic

Select this option to change the default 3D view to use the perspective projection automatically. The option to change the view to perspective is available in the View toolbar.

Background Color Select the fill color of the Viewer background. The background can be colored with a single color or gradient fill. The color change will affect EDEM Creator, Simulator, and Analyst.
User Logo Select the Enable checkbox to display a custom logo.
Logo File Path Click the icon to browse to the path of the logo file.
Scaling in Width Use the scaling options to position, scale, and specify the opacity as required.

Contact Models Browse to the location of the custom (user-defined) contact models. For more information about user-defined models, see the EDEM Programming Guide.
Particle Body Force Browse to the location of custom (user-defined) particle body force models.
Particles Browse to the location of particles saved independently of the model for reuse in other projects.
Factories Browse to the location of any user-defined factories.
Geometry Import Temporary File Location Override Select the checkbox to change the temporary file location used during the Geometry import process. Use this option only if there is an issue with using the default TEMP file location.
Alternate Windows import method Select the checkbox when you import a file using Windows. A command line window is displayed and the command hmbatch import is executed, and you can view the output. However, the import operation is executed as normal.
Mouse 3D Configuration These options allow you to modify the sensitivity of the 3D mouse in EDEM. These options allow you to adjust how much the model will move or rotate per movement of the space mouse.
Mouse Configuration
Camera Actions Change the mouse button and modifier key to pan, track, zoom, and rotate the camera. Modifier keys assign keys to perform the specified camera action.
Note: Select any unique combination of three mouse buttons and three keys for each motion.
Rotate on Axis Change the mouse button and modifier key used to rotate on an axis. You can also set rotation on the model or screen axis for both horizontal and vertical rotations.
Bin Control Select an option from the Bin Control Modifier dropdown list to change the color from blue to green. Select the Pan, Track, Axis Locked Rotation, and Free Rotation options using the Bin Control Modifier (default Ctrl) to move the bin.
Mouse Sensitivity Select the Invert Zoom checkbox to switch the direction in which the scroll wheel zooms in or out.
Select the Track and Zoom options to alter the mouse sensitivity independently. You can also specify modifier keys for each sensitivity setting.
Rendering Options
Render all using legacy display Select the checkbox if EDEM cannot use the Computer Graphics Card. This is applicable when using Remote Desktop or EDEM on computers with out-of-date graphics card drivers.
Reduce new template details during camera movement Select the checkbox to speed up the manipulation of the EDEM Viewer when using particle templates. Particles will be visualized as spheres while the view is being adjusted and then switch to templates when the view is fixed.
Display Templates Select the 3D CAD files to be used as particle templates.

You use templates as a guide (outline) to help define the shape of your particle in EDEM Creator as well as providing, if required, the shape for calculation of the Center of Gravity and mass moments of inertia, or as a display option in EDEM Analyst.

When a model containing a particle template is saved, an extra file (.ptf) is created. If this file is deleted, the template information will no longer be stored within the model.

Suppress Warning Messages Select the Suppress Deprecated Contact Model Warning Messages checkbox to hide warning messages about deprecated contact models. This reduces the number of times you will see a warning message if you are using these deprecated contact models for simulations. However, you will not see any future warnings about them being removed or other models which are marked as deprecated.
Simulator Engine
Engine Default Settings Select an engine from the Default Engine dropdown list. Options are: CPU Solver and GPU CUDA Solver.
Note: In EDEM Simulator, you can modify the default engine after which this information is stored for every simulation in the simulation_name.dfg file. While opening existing simulations, the engine that is displayed will have the last saved setting for the simulation.
Default Number Of Cores allows you to specify the default number of cores.

When starting a new simulation, EDEM uses the default number of the Maximum Cores available on the local PC. This can be specified once for every user after which EDEM will use the default setting.

Units Select Set All to SI to use the Système International Units System throughout EDEM.
Select Set All to CGS to use the Centimeter–Gram–Second system throughout EDEM.
