|
Description
|
||
|
|
Transient solver for incompressible, turbulent flow, with implicit
|
||
|
|
coupling between pressure and velocity achieved by fvBlockMatrix.
|
||
|
|
|
||
|
|
Turbulence is solved using the existing turbulence model structure.
|
||
|
|
|
||
|
|
The solver supports dynamic mesh changes
