applySeismicVelocityMarkedSTLNodes()

void Seismic::applySeismicVelocityMarkedSTLNodes

(

Mesh *

mesh

)

Applies seismic velocity to the marked seismic nodes using STL mesh.

Parameters

mesh	Pointer to the Eulerian background mesh.

disableSeismicAnalysis()

(

)

Returns the seismic acceleration.

Returns

Eigen::Vector3d& Reference to the seismic acceleration vector.

getAccumulatedVelocity()

const Eigen::Vector3d & Seismic::getAccumulatedVelocity

(

)

Returns the accumulated seismic velocity.

Returns

Eigen::Vector3d& Reference to the accumulated velocity vector.

getSeismicAnalysis()

SeismicAnalysis & Seismic::getSeismicAnalysis

(

)

Provides access to the current seismic analysis parameters.

Returns

SeismicAnalysis& Reference to seismic analysis information.

getSeismicData()

SeismicData & Seismic::getSeismicData

(

)

Provides access to the loaded seismic data.

Returns

SeismicData& Reference to the seismic data structure.

getSeismicNodeIndices()

const std::vector< int > & Seismic::getSeismicNodeIndices

(

)

Returns the list of seismic node indices.

Returns

const std::vector<int>& Reference to the indices of seismic nodes.

isSeismicNode()

bool Seismic::isSeismicNode

(

int

nodeId

)

Checks if a node is marked as seismic.

Parameters

nodeId

Node index to check.

Returns

true if the node is a seismic node, false otherwise.

markSeismicNodes()

void Seismic::markSeismicNodes	(	double	epsilon,
		Mesh *	mesh )

Marks the nodes that will receive seismic loading.

Parameters

epsilon	Grid dimension factor threshold to mark nodes as seismic nodes.
mesh	Pointer to the mesh where nodes are defined.

setSeismicAnalysis()

void Seismic::setSeismicAnalysis

(

const SeismicAnalysis &

info

)

Sets the seismic analysis configuration.

Parameters

info	Seismic analysis information to set.

setSeismicData()

void Seismic::setSeismicData

(

)

Loads seismic data from the file specified in the model configuration.

This function reads the seismic input file defined in the JSON configuration and stores the time and acceleration data into the global SeismicData structure.

updateSeismicVectors()

void Seismic::updateSeismicVectors	(	const double	currentTime,
		const double	dt )

Updates the accumulated seismic velocity and acceleration based on the current time and time step.

Parameters

currentTime	Current simulation time (s).
dt	Simulation time step (s).

Note

This function updates the global accumulatedVelocity variable with the seismic velocity
