Major Discussion Issues

List of Problems that Need Discussion

• MeshData or EquationSystems can both be used (only one tested) but which strategy provides the best approach.

  • MeshData

    Pros:

    • More Natural since we are simplifying defining data at grid locations
    • Simpler less heavyweight implementation

    Cons:

    • No interpolation
    • Few people use it so it may be buggy.
    • Only seems to work with UNV mesh format (not with xta for sure)

  • Equation Systems

    Pros:

    • Works with a variety of mesh types
    • Provides a natural means of interpolation
    • Used more frequently by libMesh developers so perhaps less buggy.

• CellML implementation completed by Jagir

  • What is the status and can we get going soon on this?

• Overall problem setup (reading in problem description)

  • Are we going to use a perl framework? python? just C++?
  • How will we use first bullet with this work? Translating all of old examples to new libMesh examples?
  • How will users run examples? Can we start thinking about this? It may help direct development of OpenCMISS.

• Monodomain/Bidomain Class

  • Does it even make sense to create a new bidomain class or is it more natural to just use EquationSystems?

• Parallel Mesh Class

  • While libmesh did not distribute the mesh (it was copied to each node) when we were evaluating it, this is currently being actively worked on by libmesh developers.
