The proximity_effects branch uses FastHenry2 to calculate frequency dependent Resistance, [R], and Inductance, [L], matrices which include proximity effects. The frequency dependent [R] and [L] are then used to develop improved cable models which incorporate proximity effects. INSTALLATION NOTES: The software in the proximity_effect branch is compiled in exactly the same way as the original SACAMOS software. fasthenry will need to be installed and fasthenry executable directory must be in the users $PATH The SACAMOS/bin directory must also be in the users $PATH so as to be able to run write_FH_input_file which creates input files for fasthenry.
