Uniaxial Compression of Bulk Material Using Flexible Plate
Uniaxial compression of bulk material using a flexible plate via EDEM-FEA coupling is used for studying how granular or bulk materials behave under vertical compression by a deformable (flexible) structure. The granules are modelled using EDEM, while the compressing plate, enclosed box and punch is modelled as deformable…

Nut Mixing and Packaging System Simulation in EDEM - Material Dosing
A significant proportion of food produced globally is never consumed, with around 14% lost between production and retail [1]. While food loss can occur at various stages of the supply chain, improving bulk material handling in food processing—through virtual testing and system optimization—can help reduce losses and…

Antenna Arrays & Beam Steering in Altair Feko
The creation of antenna arrays in Feko is simple. In addition to the obvious method of manual "Copy & Translate" (where you have to create the ports and suggestions again or create a script using "macro recording"), there is the more elegant method using an Application Macro in CADFEKO: The required application macro has…
