Detailed Description

Interface of a mesh block.

Blocks are created via IMeshMaterialMng::createBlock().

Blocks cannot be destroyed and must be created during initialization.

The concept of a block is optional and it is not necessary to have blocks to use environments and materials.

A block is characterized by a name (name()), a cell group (cells()), and a list of environments (environments()).

Note that theoretically the cell group (cells()) is independent of the list of environments, but for reasons of consistency, it is preferable that this group corresponds to the union of the block's environments. However, no verification of this consistency is performed.

It is possible to use an instance of this class as an argument to ENUMERATE_ENV or to ENUMERATE_ALLENVCELL.
