Simulation

The LSP simulation team developed a universal and anisotropic platform of simulation, containing three simulation modules:

  • FEM (finite element modelling)
  • PTM (percolation threshold modeling) and
  • ENM (electrical networks modelling).

After constantly updating, the simulation platform performs the following features:

  • Anisotropy (orientation);
  • High degree of flexibility;
  • High degree of automation;
  • High efficiency: Under the same magnitude of mesh and computing environment, our platform needs only 1/3 the time of other similar simulation program;
  • High accuracy: All parameters and results can be accurate up to 12 decimal places;
  • Very low error rate (less than 0.01%).

In 2018, Prof. Schubert published a pure theoretical work “Novel theoretical self-consistent mean-field approach to describe the conductivity of carbon fiber filled thermoplastics” (mats.201700104) with a novel theoretical approach to describe the resistivity (conductivity) of carbon fiber (CF) composites as a function of orientation, degree of filling and aspect ratio below percolation threshold. Shortly after the publication of the theoretical work, the LSP simulation team demonstrated the validity of the above described work (mats.201700105) by computer simulations. The results are also published in journal “Macromolecular Theory and Simulations”.

In 2019, the LSP simulation team ultilized the periodic boundary condition of the simulation. The results will also be compared to previous work and other theoretical models. The finite size effect of the simulation will be evaluated; simulations with different system parameters are carried out to evaluate various simulation conditions. The work is again published in Macromolecular Theory and Simulations.
