Detailed Description

Class that represents disjoint part of computational domain (or domains). It consists of one integer value but provides access to other data stored in RegionDB. In particular provides string label and integer ID (unordered) further it provides fast (inlined) methods to: 1) detect if the region is the bulk region or boundary region 2) return index (this is used to select correct Field, possibly we can distinguish boundary_index and bulk_index)

Implementation: currently we number bulk regions by odd indices and boundary regions by even indices.

Types of region in mesh (bulk or boundary)

Enumerator

Constructor & Destructor Documentation

◆ Region() [1/3]

Region::Region ( )
inline

Default region is undefined/invalid.

Definition at line 159 of file region.hh.

◆ Region() [2/3]

Region::Region ( RegionIdx  r_idx,
const RegionDB db 
)
inline

This should be used for construction from known RegionIdx. (e.g. in Mesh) Do not use unless you can not get Region in other way.

Definition at line 165 of file region.hh.

◆ Region() [3/3]

Region::Region ( unsigned int  index,
const RegionDB db 
)
inlineprotected

Create accessor from the index. Should be private since implementation specific. We need some way how to iterate over: all regions, boundary regions, bulk regions - solution: have specific RegionSets for these three cases.

Definition at line 201 of file region.hh.

Member Function Documentation

◆ comp()

static bool Region::comp ( const Region a,
const Region b 
)
inlinestatic

Comparative method of two regions.

Here is the caller graph for this function:

◆ db()

const RegionDB& Region::db ( )
inline

Returns static region database. Meant to be used for getting range of global, boundary, and bulk region indices.

Definition at line 189 of file region.hh.

◆ dim()

unsigned int Region::dim ( ) const

Returns dimension of the region.

Definition at line 42 of file region.cc.

Here is the caller graph for this function:

◆ id()

unsigned int Region::id ( ) const

Returns id of the region (using RegionDB)
