The function object will operate on both kinematic ( ) and static pressure ( ) fields, and the result is written as a volScalarField.
The modes of operation are:
Mode | calcTotal | calcCoeff |
---|---|---|
Static pressure | no | no |
Total pressure | yes | no |
Pressure coefficient | no | yes |
Total pressure coefficient | yes | yes |
Example of function object specification to calculate pressure coefficient:
pressure1 { type pressure; libs ("libfieldFunctionObjects.so"); ... calcTotal no; calcCoeff yes; }
Property | Description | Required | Default value |
---|---|---|---|
type | type name: pressure | yes | |
field | Name of the pressure field | no | p |
U | Name of the velocity field | no | U |
rho | Name of the density field | no | rho |
result | Name of the resulting field | no | derived from p |
calcTotal | Calculate total coefficient | yes | |

calcCoeff | Calculate pressure coefficient | yes | |
pInf | Freestream pressure for coefficient calculation | no | |
UInf | Freestream velocity for coefficient calculation | no | |
