Numerical Tools

Besides a long list of physics and infrastructure modules, the ITM-TF also provides a variety of numerical tools like interpolation/extrapolation routines, grid generation routines, and coordinate system transformations.
Most of these tools are new developments which are currently summarized under task WP10-ITM-IMP12-ACT15.

List of numerical tools, independent of the ITM datastructures

• interpos (svn, gforge, external webpages)

  Provide an easy, flexible and precise routine for interpolation and calculation of derivatives and integrals on a new mesh. Allows for extrapolation as well. Includes smoothing based on cubic spline with tension, minimizing second derivatives.

• dierckx (svn, gforge, external webpages)

  DIERCKX is a package of Fortran subroutines for calculating smoothing splines for various kinds of data and geometries, with automatic knot selection [Paul Dierckx, Curve and Surface Fitting with Splines, Oxford University Press, 1993].

• l3interp (svn, gforge)

  1D interpolation 3rd order Lagrange interpolation library, including derivatives.

• bsplines (gforge)

  Generalized splines of any order on irregular grids for interpolation and solving PDEs with Finite Element Methods

• Trimesh (svn, gforge)

  (Under construction). Reads a scalar field from the equilibrium data and generates a field-aligned mesh using Delaunay triangulation.

List of numerical tools that dependens of the ITM datastructures

• ITM toolbox (svn, gforge)

  Including check_equilibrium, cubint and equilibrium_augmenter (also wrapper to l3interp).

• grid tools (svn, gforge)

  Tools for handling the grid-cpo.

• FIFE (svn, gforge)

  FIeld and Flux Evaluation, using data from CPO equilibrium, also extrapolating into vacuum region.

• equilibriumfit (svn, gforge)

  Fill in missing information into equilibrium CPO.

List of generic computational tools

• CPO tools (svn)

  Library with various tools for handling CPO: copy_structures, deallocate_structures, diff_structures, euitm_printcpo, is_set_structures, printcpo, printcpoargs, read_structures, size_of_structures, write_structures error_analysis

• Fortran Assertion Module (ITM webpages, svn)

  Handling assertion and error handling. E.g. for asserting the validity of input.

• Code parameters (ITM webpages, gforge)

  An F95 library for parsing XML coded code parameters (to help incooparating xml-code parameters into Fortran codes).

• muxdemux (gforge)

  Kepler actors used to extract/import a single signal (or a set of signals) from/into a CPO

• visit_visu (gforge)

  Visualization of CPO fields through a VisIt plug-in
