Hello everyone, Since I am dealing with a fluid-structure interaction system using a fully coupled approach. Degrees of freedom are displacement and pressure. The Jacobian matrix is ​​block-wise and has the following form: [K Q ] [ Q(T) H ] where K is the stiffness matrix an

i am using the implimenation by Jaekwang Kim to model polymer flows. The major change that I want to do is to output convergence tables like in Step-7 and Step-22, which means I have to have an ExactSolution. The code is encountering an error because the dimension of the solutions do not match
