Request atoms on which the calculation depends.

◆ requestAtoms() [2/2]

void PLMD::ActionAtomistic::requestAtoms ( const std::vector< AtomNumber > &  a,
const bool  clearDep = true 
)
inherited

Request an array of atoms.

This method is used to ask for a list of atoms. Atoms should be asked for by number. If this routine is called during the simulation, atoms will be available at the next step MAYBE WE HAVE TO FIND SOMETHING MORE CLEAR FOR DYNAMIC LISTS OF ATOMS

◆ retrieveAtoms()

void PLMD::ActionAtomistic::retrieveAtoms ( )
virtualinherited

◆ runFinalJobs()

virtual void PLMD::Action::runFinalJobs ( )
inlinevirtualinherited

RunFinalJobs This method is called once at the very end of the calculation.

The set of all Actions in run for the final time in forward order.

Reimplemented in PLMD::vesselbase::ActionWithAveraging, PLMD::analysis::AnalysisBase, PLMD::gridtools::ConvertToFES, PLMD::analysis::ReadDissimilarityMatrix, and PLMD::gridtools::GridPrintingBase.

◆ setAtomsDerivatives()

void PLMD::ActionWithVirtualAtom::setAtomsDerivatives ( const std::vector< Tensor > &  d)
inlineprotected

Set the derivatives of virtual atom coordinate wrt atoms on which it dependes.

◆ setBoxDerivatives()

void PLMD::ActionWithVirtualAtom::setBoxDerivatives ( const std::vector< Tensor > &  d)
protected

Set the box derivatives.

This should be a vector of size 3. First index corresponds to the components of the virtual atom. Notice that this routine subtract the trivial term coming from cell deformation since this term is already implicitly included. Indeed, if the vatom position is a linear function of atomic coordinates it is not necessary to call this function (implicit term is fine) (e.g. vatom::COM and vatom::Center). On the other hand if the vatom position is a non-linear function of atomic coordinates this should be called (see vatom::Ghost).

◆ setBoxDerivativesNoPbc()

void PLMD::ActionWithVirtualAtom::setBoxDerivativesNoPbc ( )
protected

Set box derivatives automatically.

It should be called after the settomsDerivatives has been used for all single atoms.

Warning
It only works for virtual atoms NOT using PBCs! This implies that all atoms used + the new virtual atom should be in the same periodic image.

◆ setCharge()

void PLMD::ActionWithVirtualAtom::setCharge ( double  c)
inlineprotected

Set its charge.

◆ setExtraCV()

void PLMD::ActionAtomistic::setExtraCV ( const std::string &  name)
inlineprotectedinherited

◆ setForcesOnAtoms()

void PLMD::ActionAtomistic::setForcesOnAtoms ( const std::vector< double > &  forcesToApply,
unsigned  ind = 0 
)
inherited

Add the forces to the atoms.

◆ setGradients()

◆ setGradientsIfNeeded()

void PLMD::ActionWithVirtualAtom::setGradientsIfNeeded ( )

◆ setMass()

void PLMD::ActionWithVirtualAtom::setMass ( double  m)
inlineprotected

Set its mass.

◆ setOption()

◆ setPosition()

void PLMD::ActionWithVirtualAtom::setPosition ( const Vector pos)
inlineprotected

Set position of the virtual atom.

◆ updateUniqueLocal()

void PLMD::ActionAtomistic::updateUniqueLocal ( )
inherited

updates local unique atoms

◆ warning()

void PLMD::Action::warning ( const std::string &  msg)
inherited

Issue a warning.
