The functions in these modules are written in such the function names and attributes are very generic (get_structure (), molecular_dynamics (), version) but the functions are written to handle LAMMPS specific input/output. Parameters WebYour Tdamp and Pdamp parameters are quite high. Values equal to 100 timesteps for Tdamp and 1000 timesteps for Pdamp should work better. In order to lower the initial pressure add fix box/relax before minimization. You can output the data using fix print with "file" keyword. 4 votes 1 thanks Siegfried Fritzsche I am not familiar with this software.
