Lipid membrane

Lipid membrane is a typical example of the usage of SPICA force field. In this tutorial, we will show how to generate initial PDB files at both CG and AA level, and how to convert those PDB files to LAMMPS compatible input file. For the sake of simplicity, we show the system containing only a single lipid type (i.e., DOPC) and water. (But the generalization of multiple-lipids mixture system is just straightforward.)


  1. Prepare initial configuration
  2. Convert PDB file to LAMMPS input file
  3. Running simulation
