The Select Model dialog is the starting point for configuring a simulation in GranDEM. It allows users to activate the Continuous Fluid Phase (CFD), the Discrete Particle Phase (DEM), and define the coupling mechanisms between them. Depending on the selected options, GranDEM can perform pure CFD si…

The flow behaviour of materials is fundamentally characterised by their physical properties. Therefore, material properties of Eulerian fluids (liquid or gas) and Lagrangian particles (liquid or solid) during CFD flow simulations are extremely important while simulating system flow behavior. The Eu…

 This selection on the left pane is used after a simulation run has completed and output result data is available for paraview post-processing and visualization study. On selecting this the middle pane appears as shown in Fig. 11.1. Here in this feature various data type files can be loaded in…

On the Main UI ‘Select Model’ setting from the left pane. Under the continuous phase drop down menu election for the Eulerian fluid flow method can be made or set off.If Fixed field, single phase Eulerian or single phase External (Fluent) is selected the user can switch on the fluid heat transfer a…

On the Main UI, select ‘Material Properties’ from the left pane. This causes the component materials adding additional tabs in the middle pane to appear. This consists of the buttons ‘Add component’ and ‘Delete component’. Using the ‘Add component’ button new components can be added successive…

6.1 Injection Initialization – Specific Point InjectionThe Specific Point Injection method is used to introduce particles into the computational domain from one or more user-defined locations. Each injection point represents a particle source where particles are generated with specified physical pr…

  The output path and output time interval needs to be set using the check boxes at the top. The output path is the path where the output data will be written.Check boxes for time step size, DEM steps/Time step, Number of time step simulations and End time have been provided in the center…
