Enumeration Type Documentation

◆ cs_cdo_system_block_type_t

enum cs_cdo_system_block_type_t

type of block composing a (block) matrix

Enumerator
CS_CDO_SYSTEM_BLOCK_DEFAULT	Simplest block type. One matrix inside a block.
CS_CDO_SYSTEM_BLOCK_SPLIT	The block is described by several (sub)matrices.
CS_CDO_SYSTEM_BLOCK_UNASS	The block is unassembled so that there is no matrix and related structures to describe this type of block. For instance, this block can be associated to the pressure block in some strategy for solving sadle-point problems.
CS_CDO_SYSTEM_BLOCK_EXT	External way to define a block. This block does not rely on the generic function to assemble and build the associated structures. For instance, it corresponds to the full assembly strategy in case of a saddle-point problem.
