- relocate some standard functionality to TimePaths to allow a lighter means of managing time directories without using the entire Time mechanism. - optional enableLibs for Time construction (default is on) and a corresponding argList::noLibs() and "-no-libs" option STYLE: - mark Time::outputTime() as deprecated MAY-2016 - use pre-increment for runTime, although there is no difference in behaviour or performance.

Description
|
|
Transient solver for incompressible, turbulent flow of Newtonian fluids
|
|
on a moving mesh.
|
|
|
|
\heading Solver details
|
|
The solver uses the PIMPLE (merged PISO-SIMPLE) algorithm to solve the
|
|
continuity equation:
|
|
|
|
\f[
|
|
\div \vec{U} = 0
|
|
\f]
|
|
|
|
and momentum equation:
|
|
|
|
\f[
|
|
\ddt{\vec{U}} + \div \left( \vec{U} \vec{U} \right) - \div \gvec{R}
|
|
= - \grad p + \vec{S}_U
|
|
\f]
|
|
|
|
Where:
|
|
\vartable
|
|
\vec{U} | Velocity
|
|
p | Pressure
|
|
\vec{R} | Stress tensor
|
|
\vec{S}_U | Momentum source
|
|
\endvartable
|
|
|
|
Sub-models include:
|
|
- turbulence modelling, i.e. laminar, RAS or LES
|
|
- run-time selectable MRF and finite volume options, e.g. explicit porosity
|
|
|
|
\heading Required fields
|
|
\plaintable
|
|
U | Velocity [m/s]
|
|
p | Kinematic pressure, p/rho [m2/s2]
|
|
\<turbulence fields\> | As required by user selection
|
