2021-06-21 Thread Lucas Myers
Hi Everyone, I have a problem wherein one of the terms in my PDE is a 5-component vector function \Lambda of the 5-component solution vector Q. However, I only have an explicit formula for Q as a function of \Lambda and so I am trying to write a numerical inversion class (as a `dealii::Function
