GGITLM is the Institute's TLM based time domain simulation code, distributed under an open source license. The general purpose code is capable of predicting time domain which may be subsequently transformed into the frequency domain.

Features include:

  • Frequency domain material models including an impedance boundary representation of thin layer materials (metals, CFC, metallic mesh) 
  • Multi-conductor cable model including shielded cables and frequency dependent properties
  • Large scale capability-parallel via MPI
