A two-dimensional grid search calculates the properties of geometries corresponding to a set of points in a grid of user-defined size in two dimensions. In many ways, it is analogous to the reaction coordinate method described above, although two variables are changed and not as much information is provided. The final result is an 11×11 matrix of energies (121 in all) corresponding to sites on the grid. A grid search is called for if the keywords STEP1=n.n and STEP2=m.m are on the keyword line and two coordinates are marked with "-1" as the optimization flags. They are related to STEP1 and STEP2 in order of their definition. The reaction described in this file is part of the surface describing the inversion of 1,5-hexadiene:

A reaction grid calculation will be performed if exactly two of optimization flags are marked with a "-1". The keywords STEP1 and STEP2 are also required for a reaction grid. By default, TRUSTE will be use to perform the constrained optimization at each of the grid points but this default can be overridden by BFGS, DFP, or EF. |
|
|
This is the first reaction coordinate and will be incremented and decremented by the value of STEP1. |
|
|
This is the second reaction coordinate and will be incremented and decremented by the value of STEP2. These two items will be used to construct a grid of points and optimizations will be carried out at each point on the surface. The point given in the geometry definition is the center of the grid and five steps are taken in each direction from this center point. The following list shows the values that the first and second reaction coordinates will take on. The center point is indicated by ×: Step 1 0.79 0.94 1.09 1.24 1.39 1.54 1.69 1.84 1.99 2.14 2.29 1.44 o o o o o o o o o o o 1.59 o o o o o o o o o o o 1.74 o o o o o o o o o o o S 1.89 o o o o o o o o o o o t 2.04 o o o o o o o o o o o e 2.19 o o o o o × o o o o o p 2.34 o o o o o o o o o o o 2.49 o o o o o o o o o o o 2 2.64 o o o o o o o o o o o 2.79 o o o o o o o o o o o 2.94 o o o o o o o o o o o |
This file is abbreviated to conserve space. The archive file contains the geometries corresponding to each grid point (in the order they are computed) and so contains 121 geometries. Only the first and last geometry are shown here separated by "=========" to indicate the missing geometry. A complete copy of the file is found in the test suite results directory.

This is a description of the center point of the grid, including heat of formation and gnorm. |
|
|
This is the geometry of the center point of the grid. |
|
|
This is a list of the AM1 energies of the optimized geometries at each pair of STEP1, STEP2 coordinates. Due to the size of the output, the geometries are not printed. Coordinates and information about each geometry can be found in the visualization (*.vis) file. The AMPAC GUI can be used to examine these geometries. |
|
|
This is an 11×11 matrix of the energies at the points in the order described above. Future versions of the AMPAC GUI will present this data in graphical form. |
|
|
A list of (constrained) critical points and geometries that were found during the grid search. Constrained critical points may not actually correspond to a true critical point. Critical points of interest should be reoptimized with all optimization flags set to on and a FORCE calculation performed on the resulting geometry. |
