EVALUATE_FUNCTION_FROM_GRID_VECTOR

This is part of the gridtools module

Calculate the function stored on the input grid for each of the points in the input vector/s

Examples

Glossary of keywords and components

Compulsory keywords

INTERPOLATION_TYPE

( default=spline ) the method to use for interpolation. Can be spline, linear, ceiling or floor.

Options

NUMERICAL_DERIVATIVES	( default=off ) calculate the derivatives for these quantities numerically
ZERO_OUTSIDE_GRID_RANGE	( default=off ) if we are asked to evaluate the function for a number that is outside the range of the grid set it to zero
ARG	the input for this action is the scalar output from one or more other actions. The particular scalars that you will use are referenced using the label of the action. If the label appears on its own then it is assumed that the Action calculates a single scalar value. The value of this scalar is thus used as the input to this new action. If * or *.* appears the scalars calculated by all the proceeding actions in the input file are taken. Some actions have multi-component outputs and each component of the output has a specific label. For example a DISTANCE action labelled dist may have three components x, y and z. To take just the x component you should use dist.x, if you wish to take all three components then use dist.*.More information on the referencing of Actions can be found in the section of the manual on the PLUMED Getting Started. Scalar values can also be referenced using POSIX regular expressions as detailed in the section on Regular Expressions. To use this feature you you must compile PLUMED with the appropriate flag.. You can use multiple instances of this keyword i.e. ARG1, ARG2, ARG3...
