- vThe coupled functor which provides the force. A functor is any of the following: a variable, a functor material property, a function, a post-processor, or a number.
C++ Type:MooseFunctorName
Controllable:No
Description:The coupled functor which provides the force. A functor is any of the following: a variable, a functor material property, a function, a post-processor, or a number.
- variableThe name of the variable that this residual object operates on
C++ Type:NonlinearVariableName
Controllable:No
Description:The name of the variable that this residual object operates on
FVCoupledForce
Description
FVCoupledForce implements a source term within the domain proportional to a coupled variable: where is a known scalar coefficient, is a coupled unknown value, and the second term on the left hand side corresponds to the strong forms of other kernels. In a species transport context, the value can be regarded as a reaction rate coefficient.
