{{Note| In order to use the Polarimatrix solver, you must first generate a ray database of your propagation scene using EM.Terrano's Channel Analyzer.}}
=== Simulation Types and Modes ===
EM.Terrano provides a number of different solvers and simulation modes. Its main solver is the '''3D SBR Ray Tracer'''. Once you have set up your propagation scene in EM.Terrano and have defined sources/transmitters and observables/receivers for your scene, you are ready to run a SBR ray tracing simulation. EM.Terrano offers thee simulation modes for the SBR solver:
