Nonlinear interactions between radio frequency (RF) waves and plasmas have been researched for ages. We have developed a ray tracing program coupled with the nonlinear mechanism parametric decay instabilities (PDI) called Parametric Instabilities embedded Propagation and Evolution of RF Spectrum (PIPERS). The program can calculate the propagation and absorption in the scrape-off layer (SOL) plasma of lower hybrid waves (LHW) on the basis of the nonlocal convective amplification model of a quasi-mode PDI. To analyse the energy transfer and spectral evolution of LHW self-consistently and quantitatively, the characteristics of the numerical solution of the energy conservation equations need to be studied in terms of the simulation model.
