# Domain Coupling Using DOVE Scheme

#### Assembly of overlapping domains

The DOVE scheme was designed to automatically couple different overlapping
domains so as to assemble one composite computational domain. This technique
can be used to construct computational domains of a complex topology, or as an
alternative technique to domain decomposition, commonly used for parallel
implementation on distributed memory computer platforms.

The different domains can be originally created using any unstructured grid
generator, or MulPhys native TAM grid generator, based on
the patented tool-assisted mesh generation algorithm. After that the dove-algorithm will identify the overlapping regions and *sew-together* the domains at these regions, so that they will represent one composite domain with the appropriate exchange of variables in the overlapping regions.

#### Flow through coupled domains

Here is an example of a flow in a duct consisting of two overlapping domains.
After the application of the dove algorithm the flow solvers in both domains
can exchange information on the flow-variables in the overlapping regions, thus
realizing a continuous solution in the total domain.
