Declares functions for handling orientation restraints.
Functions | |
void | init_orires (FILE *fplog, const gmx_mtop_t *mtop, const t_inputrec *ir, const t_commrec *cr, const gmx_multisim_t *ms, t_state *globalState, t_oriresdata *od) |
Decides whether orientation restraints can work, and initializes all the orientation restraint stuff in *od (and assumes *od is already allocated. If orientation restraint are used, globalState is read and modified on the master rank (which is the only rank, since orientation restraints can not run in parallel). | |
real | calc_orires_dev (const gmx_multisim_t *ms, int nfa, const t_iatom fa[], const t_iparams ip[], const t_mdatoms *md, const rvec x[], const t_pbc *pbc, t_fcdata *fcd, history_t *hist) |
Calculates the time averaged D matrices, the S matrix for each experiment. More... | |
void | diagonalize_orires_tensors (t_oriresdata *od) |
Diagonalizes the order tensor(s) of the orienation restraints. More... | |
void | print_orires_log (FILE *log, t_oriresdata *od) |
Prints order parameter, eigenvalues and eigenvectors to the log file. | |
real | orires (int nfa, const t_iatom forceatoms[], const t_iparams ip[], const rvec x[], rvec4 f[], rvec fshift[], const t_pbc *pbc, const t_graph *g, real lambda, real *dvdlambda, const t_mdatoms *md, t_fcdata *fcd, int *global_atom_index) |
Calculates the orientation restraint forces. | |
void | update_orires_history (const t_fcdata *fcd, history_t *hist) |
Copies the new time averages that have been calculated in calc_orires_dev. | |

const t_pbc * | pbc, | ||

) |
Calculates the time averaged D matrices, the S matrix for each experiment.
Returns the weighted RMS deviation of the orientation restraints.
void diagonalize_orires_tensors | ( | t_oriresdata * | od | ) |
Diagonalizes the order tensor(s) of the orienation restraints.
For each experiment eig containts first 3 eigenvalues and then the 3 eigenvectors. The eigenvalues are ordered on magnitude.
