ModelTableCylinder1D

class ModelTableCylinder1D : public feasst::ModelOneBody

A tabular potential for interactions in one cylindrical dimension. The table file is formatted as follows:

As described in ModelTableCart1D, the first line should be “site_types=” followed by a comma-separated list of the labels of each site type. The remaining lines are the individual tables for each of the site types. For example, “site_types=O,H” will then contain a line for the table of “O” sites, then another line for the table of “H” sites. Each table is given in a single line by a number of space-separated values that represent the interaction energy spanning the range of the nearest distance, r, from the cylindrical surface, scaled by the radius, R, with the range z = r/R = [0, 1] and linearly-spaced. For example, if the line contains 5 values, then z=r/R=[0, 0.25, 0.5, 0.75, 1] and the potential will be interpolated with Table1D::forward_difference_interpolation. Note that r is not the radial distance. Instead, r=0 at the radius (e.g., the inner surface of the cylinder), and r=radius at the center.

Arguments

• table_file: file name for the table.

• Cylinder arguments.
