SPRING_V0

SPRING_V0 = [real (array)]

Description: The parameter SPRING_V0 defines the rate at which the position of minimum ( $\xi_{0\mu}$ ) of the harmonic bias potential of the form: ${\displaystyle \tilde{V}(\xi_1,\dots,\xi_{M_8}) = \sum_{\mu=1}^{M}\frac{1}{2}\kappa_{\mu} (\xi_{\mu}(q)-\xi_{0\mu})^2 \; }$ is shifted, where the sum runs over all ( $M_8$ ) coordinates the potential acts upon ( $\xi_{\mu}(q)$ ), which are defined in the ICONST-file by setting the status to 8. The units of SPRING_V0 correspond to the units of coordinate the potential acts upon (e.g., ${\AA}$ for coordinates with flag R, $rad.$ for coordinates with flag A, dimensionless for coordinates with flag W, etc...). The number of items defined via SPRING_V must be equal to $M_8$ , otherwise the calculation terminates with an error message.
