Knowledge Base

Simulation objects are used to define simulation parameters like boundary conditions and mesh size.  More information about the solver algorithms can be found in the Solvers section.

icon_sims_fdtd FDTD solver

The 2D/3D FDTD solver region defines many important simulation parameters including simulation volume, boundary conditions, simulation time, and mesh size.

icon_fdtd_port FDTD Ports

The Port objects in FDTD are children of the FDTD solver region and define the ports and modes to use for S-parameter extraction.

icon_sims_override Mesh override region

The mesh override region is used to override the default mesh size in some part of the simulation region. Normally the meshing parameters are set in the Simulation region. However, if some specific meshing conditions are required in part of the simulation region, a mesh override region can be specified. For example, some simulations with metals are very sensitive to meshing, and a mesh override region may be required at the metal surface.

 

TIP: Objects which lie outside the simulation region.

Any simulation objects contained or partly contained within the simulation region are included in the simulation, while any objects which fall completely outside of the simulation region are not included in the simulation. Those physical structures (and portions thereof) lying within the simulation region are included in the simulation (i.e. the simulation is performed on that portion of the physical structure lying within the simulation region). Physical monitors and sources are treated in a similar fashion, such that any portion of a monitor or source lying within a simulation region will be used. The user is warned when at least one source or monitor falls completely outside the simulation region.
