Function1 is an abstract base-class of run-time selectable unary functions which may be composed of other Function1's allowing the user to specify complex functions of a single scalar variable, e.g. time. The implementations need not be a simple or continuous functions; interpolated tables and polynomials are also supported. In fact form of mapping between a single scalar input and a single primitive type output is supportable. The primary application of Function1 is in time-varying boundary conditions, it also used for other functions of time, e.g. injected mass is spray simulations but is not limited to functions of time.

Description
|
|
This velocity inlet/outlet boundary condition is applied to patches in a
|
|
rotating frame where the pressure is specified. A zero-gradient is applied
|
|
for outflow (as defined by the flux); for inflow, the velocity is obtained
|
|
from the flux with a direction normal to the patch faces.

\table
|
|
Property | Description | Required | Default value
|
|
phi | flux field name | no | phi
|
|
tangentialVelocity | tangential velocity field | no |
|
|
omega | angular velocty of the frame [rad/s] | yes |
|
|
\endtable
|
|
|
|
Example of the boundary condition specification:
|
|
\verbatim
|
|
myPatch
|
|
{
|
|
type rotatingPressureInletOutletVelocity;
|
|
phi phi;
|
|
tangentialVelocity uniform (0 0 0);
|
|
omega 100;
|
|
}
|
|
\endverbatim
|
|
|
|
The \c omega entry is a Function1 type, able to describe time varying
|
|
functions.
|
|
|
|
Note
|
|
Sign conventions:
|
|
- positive flux (out of domain): apply zero-gradient condition
|
|
- negative flux (into of domain): derive from the flux in the patch-normal
|
|
direction
