from pycp2k import CP2K from pycp2k.inputsection import InputSection cp2k = CP2K() # create a new input section new_section = InputSection('SECTION_NAME') # add parameters to the input section new_section.parameters['PARAM1'] = 'VALUE1' new_section.parameters['PARAM2'] = 'VALUE2' # add the section to the main input file cp2k.input.add_section(new_section)
from pycp2k import CP2K from pycp2k.inputsection import InputSection cp2k = CP2K() input_file = 'input.inp' # load input file cp2k.input.read(input_file) # retrieve an existing input section existing_section = cp2k.input.section('EXISTING_SECTION_NAME') # modify parameters in the input section existing_section.parameters['PARAM1'] = 'NEW_VALUE1' existing_section.parameters['PARAM2'] = 'NEW_VALUE2' # write the modified input file cp2k.input.write('modified_input.inp')This example shows how to load an existing CP2K input file, retrieve an existing input section, modify the parameters in the section, and then write the modified input file to disk. The input section is named 'EXISTING_SECTION_NAME' and has two parameters, 'PARAM1' and 'PARAM2', which are modified to have new values. Overall, the pycp2k.inputsection InputSection module provides a powerful and flexible interface for defining and manipulating CP2K input sections, making it a useful tool for computational chemists and material scientists.
