SLiM

The Slab Like Microtearing mode (SLiM) model

Overview

This software provides a rapid assessment of the slab-like microtearing mode using a global linear dispersion model, which takes 50ms to calculate the growth rate and frequency of a given mode on the personal computer. Potentially uses 10^-7 of the computation resources for discharge study. For detail, one can check on the site (under construction): https://www.drmcurie.com/project-page/Research_Projects/SLiM

SLiM EXE can be found from this link: https://drive.google.com/drive/folders/12e1t6liY5JztwOBOLehPoV8GbfORn_j8?usp=sharing
