CoupledODETimeDerivative
Residual contribution of ODE from the time derivative of a coupled variable.
The CoupledODETimeDerivative
is similar to the ODETimeDerivative
scalar kernel, except that the derivative acts on a different variable than the ODE is solved for.
Example input syntax
In this example, the scalar variables f
and f_times_mult
are the solutions to the coupled ODE problem:
The time derivative term for the first equation is added using a CoupledODETimeDerivative
scalar kernel, as the first equation is set to have f
as its nonlinear variable, even though f
does not appear in it!
