4-D B-splines for STRUCTURED data

Constructor & Destructor Documentation

sierra::nalu::BSpline4D::BSpline4D ( const int  order,
const std::vector< double > &  x1,
const std::vector< double > &  x2,
const std::vector< double > &  x3,
const std::vector< double > &  x4,
const std::vector< double > &  phi,
const bool  allowClipping = true 
)

Construct a 4-D BSpline, which is composed of a set of 3-D splines and a 1-D spline.

Parameters
order: Order of accuracy. Note that for higher order, interpolation times will increase. All dimensions will be splined to this order of accuracy, although in principle each dimension could be splined to a different order...
x1: vertices for the independent variable in the first dimension
x2: vertices for the independent variable in the second dimension
x3: vertices for the independent variable in the thrid dimension
x4: vertices for the independent variable in the fourth dimension
phi: value of the dependent variable at all points on the mesh implied by x1,x2,x3,x4. By convention, phi should be arranged in memory such that it varies fastest in x1 and slowest in x4. The size of phi should be equal to the product of sizes of x1, x2, x3, x4.

sierra::nalu::BSpline4D::BSpline4D ( const bool  allowClipping = true)

Construct a skeletal 4D spline.

Useful when loading splined data from disk.

sierra::nalu::BSpline4D::BSpline4D ( const BSpline4D &  src)

Copy constructor - performs deep copy.

Read a spline from an HDF5 database.

The file should be opened and an hdf5 "group" specified. This spline will be read from the specified group.

Implements sierra::nalu::BSpline.

double sierra::nalu::BSpline4D::value ( const double *  x) const
virtual

Obtain the approximation to the dependent variable given the independent variables.

Ordering is [x1,x2,x3,x4].

Write a spline to an HDF5 database.

The file should be opened and an hdf5 "group" created. This spline will be written to the specified group.
