Domain of the sub-task

Domain of the sub-task

Ver: 0

DESCRIPTION

Defines the domain of the current sub-task. By default, the sub-task covers the entire mesh.

With sub-domains specified during the mesh generation, the domain of the sub-task can be restricted to one sub-domain or a union of sub-domains.
By adding or substracting sub-domains, the user builds the domain of the sub-task.

The current domain is recalled in the header.

OPTIONS

-2
Make the current domain empty

Cancels all previous sub-domain definitions.
In some situations, it is easier to build the domain of the current sub-task in "additive" rather than "substractive" mode.

-1
Upper level menu

0
Extension to the whole mesh

Complementary option to option -2

i
Removal of sub-domain i

Removes sub-domain "i" from the current domain of the sub-task

j
Addition of sub-domain j

Adds sub-domain "i" from the current domain of the sub-task

NOTES

The domain of a sub-task can contain non-connected sub-domains.However, correct boundary conditions for the stream function in 2-D requires sub-domains made of connected, non-overlapping regions of the mesh.
