Detailed Description

template<int dim>
class Functions::InterpolatedUniformGridData< dim >

A scalar function that computes its values by (bi-, tri-)linear interpolation from a set of point data that are arranged on a uniformly spaced tensor product mesh. In other words, considering the three-dimensional case, let there be points \(x_0,\ldots, x_{K-1}\) that result from a uniform subdivision of the interval \([x_0,x_{K-1}]\) into \(K-1\) sub-intervals of size \(\Delta x = (x_{K-1}-x_0)/(K-1)\), and similarly \(y_0,\ldots,y_{L-1}\), \(z_1,\ldots,z_{M-1}\). Also consider data \(d_{klm}\) defined at point \((x_k,y_l,z_m)^T\), then evaluating the function at a point \(\mathbf x=(x,y,z)\) will find the box so that \(x_k\le x\le x_{k+1}, y_l\le y\le y_{l+1}, z_m\le z\le z_{m+1}\), and do a trilinear interpolation of the data on this cell. Similar operations are done in lower dimensions.

This class is most often used for either evaluating coefficients or right hand sides that are provided experimentally at a number of points inside the domain, or for comparing outputs of a solution on a finite element mesh against previously obtained data defined on a grid.

Note: If you have a problem where the points \(x_i\) are not equally spaced (e.g., they result from a computation on a graded mesh that is denser closer to one boundary), then use the InterpolatedTensorProductGridData class instead.

If a point is requested outside the box defined by the end points of the coordinate arrays, then the function is assumed to simply extend by constant values beyond the last data point in each coordinate direction. (The class does not throw an error if a point lies outside the box since it frequently happens that a point lies just outside the box by an amount on the order of numerical roundoff.)

Note: The use of this class is discussed in step-53.

Dealing with large data sets

This class supports the same facilities for dealing with large data sets as the InterpolatedTensorProductGridData class. See there for more information and example codes.

◆ InterpolatedUniformGridData() [1/2]

template<int dim>

Functions::InterpolatedUniformGridData< dim >::InterpolatedUniformGridData	(	const std::array< std::pair< double, double >, dim > &	interval_endpoints,
		const std::array< unsigned int, dim > &	n_subintervals,
		const Table< dim, double > &	data_values )

Constructor

Parameters

interval_endpoints	The left and right end points of the (uniformly subdivided) intervals in each of the coordinate directions.
n_subintervals	The number of subintervals in each coordinate direction. A value of one for a coordinate means that the interval is considered as one subinterval consisting of the entire range. A value of two means that there are two subintervals each with one half of the range, etc.
data_values	A dim-dimensional table of data at each of the mesh points defined by the coordinate arrays above. Note that the Table class has a number of conversion constructors that allow converting other data types into a table where you specify this argument.

Definition at line 2665 of file function_lib.cc.

◆ InterpolatedUniformGridData() [2/2]

template<int dim>

Functions::InterpolatedUniformGridData< dim >::InterpolatedUniformGridData	(	std::array< std::pair< double, double >, dim > &&	interval_endpoints,
		std::array< unsigned int, dim > &&	n_subintervals,
		Table< dim, double > &&	data_values )

Like the previous constructor, but take the arguments as rvalue references and move, instead of copy the data. This is often useful in cases where the data stored in these tables is large and the information used to initialize the current object is no longer needed separately. In other words, there is no need to keep the original object from which this object could copy its information, but it might as well take over ("move") the data.

Moving data also enables using tables that are located in shared memory between multiple MPI processes, rather than copying the data from shared memory into local memory whenever one creates an InterpolatedUniformGridData object. See the TableBase::replicate_across_communicator() function on how to share a data set between multiple processes.

◆ value()

template<int dim>

double Functions::InterpolatedUniformGridData< dim >::value	(	const Point< dim > &	p,
		const unsigned int	component = 0 ) const

overridevirtual

Compute the value of the function set by bilinear interpolation of the given data set.

Parameters

p	The point at which the function is to be evaluated.
component	The vector component. Since this function is scalar, only zero is a valid argument here.

Returns: The interpolated value at this point. If the point lies outside the set of coordinates, the function is extended by a constant.

Reimplemented from Function< dim, RangeNumberType >.

Definition at line 2715 of file function_lib.cc.

overridevirtual

Compute the gradient of the function set by bilinear interpolation of the given data set.

Parameters

p	The point at which the function is to be evaluated.
component	The vector component. Since this function is scalar, only zero is a valid argument here.

Definition at line 155 of file subscriptor.cc.

◆ n_subscriptions()

unsigned int Subscriptor::n_subscriptions ( ) const

inlineinherited

Return the present number of subscriptions to this object. This allows to use this class for reference counted lifetime determination where the last one to unsubscribe also deletes the object.

Definition at line 300 of file subscriptor.h.

◆ list_subscribers() [1/2]

template<typename StreamType >

void Subscriptor::list_subscribers ( StreamType & stream ) const

inlineinherited

List the subscribers to the input stream.

Definition at line 317 of file subscriptor.h.

◆ serialize()

template<class Archive >

		const unsigned int	version )

inlineinherited

Read or write the data of this object to or from a stream for the purpose of serialization using the BOOST serialization library.

This function does not actually serialize any of the member variables of this class. The reason is that what this class stores is only who subscribes to this object, but who does so at the time of storing the contents of this object does not necessarily have anything to do with who subscribes to the object when it is restored. Consequently, we do not want to overwrite the subscribers at the time of restoring, and then there is no reason to write the subscribers out in the first place.

Definition at line 309 of file subscriptor.h.

◆ check_no_subscribers()

void Subscriptor::check_no_subscribers ( ) const

privatenoexceptinherited

Check that there are no objects subscribing to this object. If this check passes then it is safe to destroy the current object. It this check fails then this function will either abort or print an error message to deallog (by using the AssertNothrow mechanism), but will not throw an exception.

Note: Since this function is just a consistency check it does nothing in release mode.; If this function is called when there is an uncaught exception then, rather than aborting, this function prints an error message to the standard error stream and returns.

std::atomic<unsigned int> Subscriptor::counter

mutableprivateinherited

Store the number of objects which subscribed to this object. Initially, this number is zero, and upon destruction it shall be zero again (i.e. all objects which subscribed should have unsubscribed again).

The creator (and owner) of an object is counted in the map below if HE manages to supply identification.

We use the mutable keyword in order to allow subscription to constant objects also.

This counter may be read from and written to concurrently in multithreaded code: hence we use the std::atomic class template.
