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 (modelling of electrical networks).
After the update, the simulation platform provides the following functions:
- Anisotropy (orientation)
- High flexibility
- High degree of automationHigh efficiency: Under the same size of mesh and computing environment, our platform only requires 1/3 of the time of other simulation programs.
- High precision: All parameters and results can be specified with up to 12 decimal places.
- Very low error rate (less than 0.01%).
In 2018, Prof. Schubert published a novel theoretical approach to describing the conductivity of thermoplastics filled with carbon fibers (mats.201700104) to describe the specific resistance (conductivity) of Carbon fibers (CF) composites depending on orientation, degree of filling and aspect ratio below the percolation threshold. Shortly after the publication of the theoretical work, the LSP simulation team demonstrated the validity of the work described above (mats.201700105) through computer simulations.
The results are also published in the journal “Macromolecular Theory and Simulations”.
In 2019, the LSP simulation team implemented the periodic boundary conditions of the simulation. The results are therefore compared with previous work and other theoretical models. The finite size effect of the simulation is evaluated; Simulations with different system parameters are performed to evaluate different simulation conditions. The work will be republished in Macromolecular Theory and Simulations.
