WebABSTRACT A 3D finite-difference time-domain transient electromagnetic forward-modeling method with a whole-space initial field is proposed to improve forward efficiency and flexibility. The open-source software WFTEM3D is developed based on this method with two language versions: a FORTRAN code and a MATLAB code. First, the scheme calculates … Web16.6. Gauss’s law for electric charge requires a closed surface and cannot ordinarily be applied to a surface like S1 alone or S2 alone. But the two surfaces S1 and S2 form a closed surface in Figure 16.3 and can be used in Gauss’s law. Because the electric field is zero on S1, the flux contribution through S1 is zero.
