Configuration for a legpolyvar.
The legpolyvar lets you describe a spatial function with the help of a multidimensional Legendre polynomial series, as found as basis functions in the solver elements.
The Legendre modes are read from a file in restart format (all modes written unformatted consecutively into a file).
| Type | Visibility | Attributes | Name | Initial | |||
|---|---|---|---|---|---|---|---|
| integer, | private | :: | poly_space | Polynomial space of the multidimensional polynomial (Q or P) |
|||
| integer, | private | :: | nDims | Dimensionality of the polynomial (needs to be between 1 and 3). onedimensional polynomial series only vary in X, twodimensional in X and Y. |
|||
| integer, | private | :: | degree | Maximal polynomial degree in the polynomial series. |
|||
| integer, | private | :: | iComp | State component in the given file for the data to read. The polynomial definition in the file may contain multiple quantities. iComp specifies, which of them to use for this function. |
|||
| real(kind=rk), | private | :: | origin(3) | Position of the origin corner for the box, the Legendre polynomials are to live in. |
|||
| real(kind=rk), | private | :: | extent | Extent of the box the Legendre polynomial series is defined in. |
|||
| character(len=pathLen), | private | :: | filename | Name of the file to read the polynomial coefficients from. This file needs to contain the polynomial data in the same format as in the Ateles restart files, but only a single element is considered. Layout of the data is given by poly_space, nDims and degree. |
