private subroutine interp_3D_bfields(params, Y, B, flag)

@brief Subroutine for interpolating the pre-computed, 3-D magnetic field to the particles' position.

@param[in] Y Particles' position in cylindrical coordinates, Y(1,:) = , Y(2,:) = , and Y(3,:) = . @param[in,out] B Cartesian components of interpolated magnetic field components. B(1,:)=, B(2,:)=, and B(3,:)=. @param F Cylindrical components of interpolated magnetic field components. F(1,:)=, F(2,:)=, and F(3,:)=. @param flag Flag that indicates whether particles are followed in the simulation (flag=1), or not (flag=0). @param pp Particle iterator. @param ss Species iterator.
