Autodesk ASCII Scene Export (ASE) files and Autodesk ASCII Export (ASC) files can be opened with AutoCAD and 3ds Max. Since they're text files, any text editor can be used to read the file. WebThe ase.lattice module. The module contains functions for creating most common crystal structures with arbitrary orientation. The user can specify the desired Miller index along the three axes of the simulation, and the smallest periodic structure fulfilling this specification is created. Both bulk crystals and surfaces can be created.

WebThis is done by calculating the total energy for the isolated slab and for the isolated molecule. The adsorbate is then added to the slab and relaxed, and the total energy for this composite system is calculated. The adsorption energy is obtained as the sum of the isolated energies minus the energy of the composite system.

If you are doing a surface + adsorbate calculation, select an option for the adsorbate position and enter a value for the distance the adsorbate will be placed above the surface. The options for position use the adsorbate position keywords from ASE. 4. When you are doing a surface + adsorbate calculation, additional boxes appear where the
