Single point calculation for a defined positions

[Sara]

Hi Dr David Dubbeldam,

Is there a way to compute the adsorbate-adsorbate energy for a defined XYZ coordinates for the both adsorbates? I mean I tried to put them in a box but raspa keeps changing the positions, I want it to read the exact positions in the .def file. Is that possible? it is like a single point calculation.

Use a restart-file:
Reads the positions, velocities, and force from the directory 'RestartInitial'. Any creation of molecules in the 'simulation.input' file will be in addition and after this first read from file. This is useful to loadinitial positions of cations for example, and after that create adsorbates. The restart file is written at 'PrintEvery' intervals.

Easiest is to first create a system with the desired number of molecules. Then run it to get a restart-file. Move the directory from 'Restart' to 'RestartInitial' and edit the positions. Then rerun with 'RestartFile yes' (and set 'CreateNumberOfMolecules 0' since they now come from the restart-file).
