Member Function Documentation

void sim::fdm::SimulatorIso::addSource

(

const Source &

source

)

Add new source function. 

Parameters

source

Source function.

void sim::fdm::SimulatorIso::clearSources

(

)

Remove all sources

sim::ErrCode sim::fdm::SimulatorIso::init	(	const Snapshot::Area &	snapshot_area,
		const VelModel< sim::VmParamsIso > &	vm
	)

Reinitialize simulator. 

Parameters

snapshot_area	Snapshot x and z coordinates area.
vm	Velocity model.

Returns

error code (EC_OK if all good).

sim::ErrCode sim::fdm::SimulatorIso::init	(	const Snapshot::Area &	snapshot_area,
		const VelModel< sim::VmParamsIso > &	vm,
		const Source &	source
	)

Reinitialize simulator. 

Parameters

snapshot_area	Snapshot x and z coordinates area.
vm	Velocity model.
source	Source function.

Returns

error code (EC_OK if all good).

AmplT sim::fdm::SimulatorIso::interpol_ampl ( const TimeT &  t1, const AmplT &  a1, const TimeT &  t2, const AmplT &  a2, const TimeT &  t  ) const

protected

Linear interpolation of amplitudes.

sim::ErrCode sim::fdm::SimulatorIso::operator()	(	const TimeT &	dt,
		WaveField &	wf
	)		const

Fill predefined wavefield amplitudes by finite-difference modelling. wf.header().t0 - start time of modeling. wf.header().timestep - resulted tim step. wf[i].size() - length of resulted wavefield. TA_XOP, TA_ZOP are used as coordinates of receiver points. TA_COMP (X/x, Z/z or any for z-component) is used to match required component.

Parameters

dt	Finite differencies time grid step.
wf	Resulted wavefied.

Returns

error code (EC_OK if all good).

void sim::fdm::SimulatorIso::setExecutionFlag

(

const bool

flag

)

Set calculations execution flag. 

Usefull for stop calculations from other threads.

Parameters

Flag	of execution. If false => executions (init, operator()) terminated or will not run.

virtual void sim::fdm::SimulatorIso::snapshotCallback ( const TimeT &  t, const TimeT &  tmax, const Snapshot &  snapshot  ) const

virtual

Callback function called on every operator() time step. Should be reimplemented.

Parameters

t	Current time step.
t	Maximal modelling time.
snapshot	Current snapshot.
