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…

Rollover Simulation using EDEM-MS Two-way Coupling
A rollover or overturn is a type of vehicle crash in which a vehicle tips over onto its side or roof. Rollovers have a higher fatality rate than other types of vehicle collisions. Rollovers are classified into two types: Un-tripped rollover Tripped rollover Un-tripped rollover: These are relatively rare events that may…
