CoupledForce
Description
CoupledForce 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.
The weak form, in inner-product notation, is defined as
where are the test functions and is the finite element solution of the weak formulation.
The corresponding Jacobian is
Example Syntax
The kernel block below shows a variable that is diffusing and being produced at a rate proportional to the concentration of a variable which is also diffusing.
