Conformal FDTD engine
An important tool for verification if the mesh used in simulation corresponds to the intentions of the user.
After opening the Test Mesh window we can see layer by layer how the FDTD grid has been created by the QW-Editor. For a cell pointed by a cursor, its position, cell type and filling media are shown in window status. More detailed information for each cell is provided by Media Info dialogue.

Conformal Approximations for Irregular Geometries
Classical stair-case meshing radically corrupts the physical geometry. Good shape imitation can be approximated by mesh refinement, but it drastically increases memory occupancy and simulation time.
QuickWave uses advanced conformal boundary models which allow precise and accurate modelling of curved shapes and obtaining high accuracy simulation results without time-step reduction!
