Discrete Element Model Ribbon Tab
Context-sensitive tab — appears when the Discrete Element Volume context is active, which is when a model has been made active with Make Active on its menu.
Commands available on the Discrete Element Model ribbon tab, grouped by panel.
The tab carries a single command; the simulation's own settings live in the volume's property sheet. Everything else you do with a model is on its right-click menu, and the DEM User Guide explains how to use it. The stress–strain chart has its own button: DEM Test Tab, on the Home tab.
Simulation
Start/Stop
Run the discrete-element simulation on the active volume, or halt one that is running.
This button only responds in an OpenGL 3D view, and particles are only drawn in a Vulkan 3D view. In a Vulkan view, use Start/Stop on the model's Simulation menu instead. The button also looks for an active point cloud, mesh or surface first, and does nothing if it finds one, which is the usual state after Fit To Active Outcrop.
