Scope & Technical Coverage

Area	Details
Geometry	Arbitrary meshes, interconnected grids, rods, plates, foundations, rings, shields, and connections to structures or third-party systems.
Soil Model	Uniform or multilayer soils derived from Wenner/Schlumberger tests; seasonal/resistivity scenarios; automated curve fitting.
Results	GPR, touch/step voltages, current density, conductor currents, surface potential maps, dangerous points and transfer potentials.
Compliance	Safety evaluation against IEEE Std 80 / IEC-EN 50522 / IEC 60479 with mitigation aids (surface layer, additional bonds, gradient control).
Integration	CAD-friendly import/export; consistent workflow with GSA FD, XGSA FD/TD, NETS and SHIELD for end-to-end studies.
