Most fvOptions change the state of the fields and equations they are applied to but do not change internal state so it makes more sense that the interface is const, consistent with MeshObjects. For the few fvOptions which do maintain a changing state the member data is now mutable.

Foam::fv::variableHeatTransfer
|
|
|
|
Description
|
|
Variable heat transfer model depending on local values. The area of contact
|
|
between regions (area) must be provided. The Nu number is calculated as:
|
|
|
|
Nu = a*pow(Re, b)*pow(Pr, c)
|
|
|
|
and the heat transfer coefficient as:
|
|
|
|
htc = Nu*K/ds
|
|
|
|
where:
|
|
K is the heat conduction
|
|
ds is the strut diameter
