HIGH PRIORITY

Develop a helper to build the list of Ghost elements

  • Read and allocate the required ElementGID, then build the list of elements that do not belong to the local domain and return it to the caller.

Distributed parallel write

  • Open a mesh file in write mode but only create the skeleton of the mesh structure to enable further concurrent write access.
  • Open an existing mesh file in write mode and enable concurrent block writes, thanks to the existing file structure.

STANDARD PRIORITY

Handle arbitrary degree high-order elements

  • Setup a keyword to store Pk elements.
  • Give along a routine to convert to and from well-known high-order numberings.

Solution fields comments

  • Add a procedure that would search for a string among comments.
  • Input: keyword name, physical property, free comment, wildcards.
  • Output: list of solutions keywords and particular field number.

Add IHOSol* + DHOSol* for each element kinds,

For example:

"IHOSolAtVertices", "i", "ii" // ii = degree + index in DSol

"DHOSolAtVertices", "i", "hr" // High Order solution

Topological operations

  • Add a helper to build the list of inner or surface triangles from tetrahedra
  • Add a helper to build the list of unique edges from tetrahedra
  • Add a helper to get the face neighborhood between tets and triangles
  • Add a helper to get an edge's shell of triangles or tets

Documentation

DONE

  • Indirect storage through a renumbering table for parallel reading.
  • Keyword documentation updated.
  • High-Order multiple solutions per element for DG.
  • Added ByteFlow keyword to store an arbitrary sized byte array.
  • Added two examples to read and write EGADS CAD models stores as byte flows.
  • Give a way to describe the node numbering.
  • Setup a polygon keyword that provides an arbitrary degree and number of nodes.
  • Setup a polyhedron keyword that provides an arbitrary degree and number of oriented polygons.
  • Setup a boundary polygon keyword that lists the boundary faces among the ensemble of volume polygons.
  • Create a separate helper file to be optionally compiled along the libMeshb.
  • Added a helper to allocate and read the boundary polygons.
  • Added a helper to allocate and read the polyhedra and inner polygons.
  • Added a helper that returns a polygon's degree and nodes list.
  • Added a helper that returns a polyhedron's degree and face indices list.
  • Write the helper's documentation.
  • Added an example that converts and fuses all surfaces and volume elements to polygons and polyhedra.
  • Added a helper to tesselate a polygon into a set of triangles made of nodes and edge visibility flags.
  • Added a set of keywords for each kind of element that stores the number of vertices and their barycentric coordinates.
  • Added a section about the AIO mode (Asynchronous Input Output).
  • Added a helper that evaluates the quality of a mesh numbering in terms of efficient cache reuse and inner concurrency.
  • Added F77 API to GmfSetHONodesOrdering
  • Completely rewrote the whole Fortran API because GFortran dropped support for C variable argumeents procedure.
  • H.O. tests converted to Fortran by Christophe Peyret
  • Added a helper that cuts a polyhedron through a plane and generates the intersection's triangulated mesh in an STL-like format.
