Toolbox for numerical discretizations of PDEs

• General Mesh class for a mesh of arbitrary dimension
• Mesh3D, Mesh2D, and Mesh1D for general 1, 2, and 3D mesh
  • enables reading of standard mesh file formats (MSH, NEU, XML, CAS)
• Domain class to hold parallelization information
• SimulationData base class for data output from a general Mesh
  • implementation by HDF5, VTK
• utilities
  • Timer
  • LookupTable
  • SignalGenerator
  • SignalProcessing

simbox's Issues

lookup table

The lookup table class could probably be implemented better. Could do a specific LUT for "mapped" data that is too big for memory. Then another LUT for data this is to be read in.

RegularMesh

create RegularMesh 2D and 3D derived from Mesh2D and Mesh3D. This should know how to point to neighbor cells/nodes in each direction. Implement morton ordering. Need a RegularDomain class to accompany this.

MultiSetContainer inherits container functions

should be able to call base container functions on individual subsets of the multisetcontainer.

For example, if the base container has a method: container.vectorize(),
then the set_container should be able to do this: set_container::set("my_set").vectorize()

Domain implementation

Implement a domain as a collection of meshes

mesh property generation by point query

generate properties over the mesh points by doing a contains_point() query for every mesh node. Can be extended to elements by doing multiple contains_point()

GradedMesh

rectangular mesh with variable spacing at each point. Pretty simple addition but can make a difference to solution quality and time to solve
