A kernel for calculating the residual and Jacobian contributions from a function

[alimostafavi24]

Dear MOOSE experts,

Is there any kernel to calculate the residual and Jacobian contributions from a given function (f) in the framework?

I am looking for something similar to SplitCHParsed where it calculates the contributions from df/dc. I need something that does not take the derivative of the function.

Thanks,

Hello

Do you mean a CoupledForce like kernel which takes a Function as an input?

Or do you mean an example of any kernel using a Function in the code?

Hello,

Sorry for the late reply. I am mostly looking for a CoupledForce like kernel which takes a Function as an input and computes the resiudal and jacobian contributions for a given function.

Thanks,
Ali

forward the function through an auxvariable with a FunctionAux
then use this kernel
