Grids

The Grid is the computational domain of the simulation. It can be 1D, 2D or 3D cartesian, and if working with a 2D electrostatic simulation, cylindrical coordinates are also available.

Only objects that are inside of the grid will be simulated, those outside are ignored.

The grid can be uniformly discretized based on the number of cells specified for the respective axial direction. It can also be variably discretized based on the number of cells and the relative cell sizing at specific points in the respective axial direction.

Note

The grid, or grid faces should never be deleted from the simulation. If they are it will be necessary to recreate the simulation file
