The LSP simulation team is developing a universal and anisotropic simulation platform with three simulation modules:

FEM (finite element modeling)
PTM (percolation threshold modeling)
ENM (modeling of electrical networks).

After years of modification and update, the simulation platform contains the following functions:

Anisotropy (orientation)
High flexibility: The filler geometry and orientation distribution can be manually set
High degree of automation: The simulation platform will detect if the result is reasonable, for abnormal experimental results or unexplained interruptions, the simulation platform will send a report to the experimenter.
High efficiency: With the same size of mesh and computing environment, our platform only needs 1/3 the time of former simulation programs.
High accuracy: all parameters and results can be specified with up to 12 decimal places.
Very low error rate (less than 0.01%).

The simulation team also did some analysis on the finite element analysis algorithm.
