MultiDomainGrid

This is the 2.6.0 release of MultiDomainGrid, a meta grid build on top of the DUNE grid interface. See the file README for further details including license information.

If you need help, please ask via Dune GitLab If you find bugs, you can also submit them to the bugtracker. Even better, if you have managed to fix a problem, open a merge request to get your patch merged into the library.

Changes

• Modernize old template-metaprogramming techniques !47 (merged)
• Compatibility with dune 2.10 core modules !54 (merged) !55 (merged)

MultiDomainGrid 2.9

• Grid factory is now smarter on checking the maximum number of SubDomains !48 (merged), !45 (merged)
• MultiDomain entity cast to SubDomain entity is now SFINAE friendly !42 (merged)
• Remove deprecated MultiDomainMCMGMapper::update() !51 (merged)
• Add forward declaration of grid factory !44 (merged)
• Add factory and gmsh reader specializations for MultiDomain grids !43 (merged), !46 (merged)
• Clean up old C++11 syntax !26 (merged)
• Grid can now take ownership of the host grid !40 (merged)
• Fix equal comparison of subdomain entities !41 (merged)
• Compatibility with dune 2.9.0 core modules !35 (merged), !36 (merged), !37 (merged), !38 (merged), !39 (merged)

MultiDomainGrid 2.8

• Fix bug where level index sets where not updated after grid adaptation !27 (merged)
• Add entity iterator capabilities !28 (merged)
• Compatibility with dune 2.8.0 core modules !32 (merged)
• Remove dune-typetree dependency !31 (merged)

MultiDomainGrid 2.7

MultiDomainGrid 2.6

• Bump build toolchain requirements to GCC 5 and CMake 3.1.0.

• Compatibility with DUNE 2.6.0.

• All deprecated functionality removed.

MultiDomainGrid 2.4

• Bump compiler requirements to GCC 4.7.

• Compatibility with DUNE 2.4.0.

• New implementation of per-codim data containers on top of std::tuple.

• Removed Boost dependency.

• New dependency on TypeTree for tuple iteration infrastructure.

• Copyable entities and intersections as required by dune-grid 2.4.0. Apart from the new API presented to the user, there are some important additional consequences:

  • The characteristics of the performance overhead of using MultiDomainGrid are different: Initial measurements show that using just a MultiDomainGrid is slightly slower than before (about 5-10%), but when stacking multiple meta grids is much less problematic.

  • The underlying host grid of a MultiDomainGrid must have been ported to the new copyable entity and intersection APIs. Unported grids will cause compilation errors. Apart from the old ALUGrid bindings (which are deprecated in DUNE 2.4), all important grids have been ported for the 2.4 release.

  • The method multiDomainEntityPointer() has been removed from the MultiDomainGrid class. It has been replaced by the method wrapHostEntity() which takes a reference to a host entity and returns a MultiDomainGrid entity.

• Release history

  • 2.4.0-rc1 Initial release candidate.

MultiDomainGrid 2.3

• First "official" release.

• New storage policy that supports specifying the maximum number of subdomains at runtime.

• Support for building with CMake.

• Compatibility with DUNE 2.3.x.

• Some minor bugfixes.

• Release history

  • 2.3.1 Final release, compatible with DUNE 2.3.1.

  • 2.3.0-rc2 Fix stupid build system problems

    • distribute documentation files
    • make sure there is a README file; otherwise make dist breaks
    • fix pkg-config info

  • 2.3.0-rc1 Initial release candidate

Caveats

The following list is a non-exhaustive overview of possible problems you might encounter with the current release.

General

• Compile times can be really long for non-trivial problems. Some developers have had good success with using the clang compiler instead of GCC during development and bug-testing to reduce compile times.
