Hello, all.
Playing around with some tutorial examples in OF, i've stumped with some weird type of fixedValue boundary condition specification. Something like this: exampleBC{ type fixedValue; value $internalField }; I've been searching in the guides for months, but never found anything about the $internalField operator. What is the meaning of it? And where can I find lectures about it? Thanks in advance!!! |

You can refer previously defined variables in OpenFOAM dictionaries.
In this case, you would have something like Code:
internalField uniform 0; |

Hi hfsf
Although Bernhard reply was somehow sufficient and complete. I can add that for instance for pressure of the domain in free jets that exit to the non-confined environments; we can use this type of boundary condition. The internal field value is 1e05 pa. Regards Bobi |

dear all.
i have a question for this $internalField boundary condition. if the initial condition is defined as Code:
internalField nonuniform List<scalar> …… boundaryField { outlet { type fixedValue; value $internalField; } } will the boundary field value keep equal to the value in the patch-connected cell? could someone plz give me some hints? thanks in advance! /Karekle |
