Anwendung
- There are several ways to invoke the command:
- Press the
Electric Charge Density button. - Select the Model → Electromagnetic Boundary Conditions → Electric Charge Density option from the menu.
- Press the
- Select a mode:
- Interface - free surface charge density (to be applied to surfaces in 3D analyses and edges in 2D analyses) allowing modeling of charged layers, equivalent to Electric Flux Density in Electrostatic potential boundary condition, specify Density
- Source - free volume charge density (to be applied to solids in 3D analyses and surfaces in 2D analyses), specify Density
- Total Interface - total charge distributed across the free surface, specify Total Charge
- Total Source - total charge distributed across the free volume, specify Total Charge
- Press the Add button.
- In the 3D View select the object the load should be applied to. introduced in 1.1: To remove objects from the selection, press the Remove button.
