| 8.1.1 – Prescribed temperature condition | |||
When we are handling prescribed temperature conditions, we have the equation for the fictitious volume. And the average between the fictitious volume and the adjacent volume must be equal to temperature at boundary, as shown at faces of the domain: |
|||
| East face: | |||

|||
 |
(8.1.1.1) |
||
Therefore |
|||
 |
(8.1.1.2a) |
||
 |
(8.1.1.2b) |
||
 |
(8.1.1.2c) |
||
 |
(8.1.1.2d) |
||
| West face: | |||

|||
 |
(8.1.1.3) |
||
Therefore |
|||
 |
(8.1.1.4a) |
||
 |
(8.1.1.4b) |
||
 |
(8.1.1.4c) |
||
|
(8.1.1.4d) |
||
| North face: | |||

|||
 |
(8.1.1.5) |
||
Therefore |
|||
|
(8.1.1.6a) |
||
 |
(8.1.1.6b) |
||
 |
(8.1.1.6c) |
||
|
(8.1.1.6d) |
||
| South face: | |||

|||
 |
(8.1.1.7) |
||
Therefore |
|||
|
(8.1.1.8a) |
||
 |
(8.1.1.8b) |
||
 |
(8.1.1.8c) |
||
|
(8.1.1.8d) |
