Customization

Medusa library support users defining custom basis types, weights, operators and more, as long as they conform to the prescribed interfaces, given in the Concepts page.

Custom operators: Biharmonic equation

Biharmonic operator $\nabla^4$ is not included in Medusa by default, but it is easy to define.

We solve the problem

$ \begin{align}

 \nabla^4 u &= f      &&\text{in } \Omega, \\
 u &= g_d           &&\text{on } \partial \Omega,\\
 \frac{\partial u}{\partial \vec n} &= g_n           &&\text{on } \partial \Omega, 

\end{align} $ where $u = TODO$ and $f$, $g_d$ and $g_n$ are computed from $u$.
