Note for now much of the docs is LLM written. This was done to save time and focus on code development. The docs have been LOOSLEY reviewed. However, the code itself has been either fully written by hand or fully reviewed. Therefore, the docs should at the moment be seen as a loose resource rather than authoratiative (and this is on top of the general ability for docs to drift)

<para><simplesect kind="note"><para>The angular momentum constraint is a global constraint that is enforced by integrating the point-wise contributions of the angular momentum density over the entire domain. The integrand is given by <formula id="57">$ j_\parallel = \rho \Omega s^2$</formula>, where <formula id="58">$s^2 = |\hat{n} × (r − r_{c})|^2$</formula> is the cylindrical radius squared, and <formula id="59">$\hat{n}$</formula> is the unit rotation axis. The solver will integrate this over the domain and compare it to the target angular momentum to enforce the constraint.</para>

A few important notes about the implementation</para>

||
<para><itemizedlist>
|
||
<listitem><para>The way the equation system plugs into the mfem backend is such that equations should only ever return point wise contributions to the residual, not a global integrated residual. This is why we return <formula id="57">$ j_\parallel = \rho \Omega s^2$</formula> as the residual, rather than <formula id="60">$ j_\parallel - J_{\text{target}}$</formula>. However we still need to subtract the target angular momentum from the integrated residual to enforce the constraint. This is done by implementing the method ::residual_offset() which returns <formula id="61">$ -J_{\text{target}}$</formula>. The backend will automatically detect and, if present, subtract this from the integrated residual to enforce the constraint.</para>
|
||
</listitem><listitem><para>The solver can choose to validate the angular momentum constraint by integrating the ::validation_integrand() over the domain and then passing this result to ::validate_integral(double result). Note that this is not specific to this equation but a feature of the overall system </para>
