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.

Member Enumeration Documentation

RegionType

enum Region::RegionType

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 158 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 164 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 200 of file region.hh.

Member Function Documentation

comp()

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

inlinestatic

Comparative method of two regions.
