Current implementation of feature-based anisotropic mesh adaptation uses the Hessian of solution's first state. Since using the Mach number to guide mesh adaptation was found to be promising in several works, a future implementation of using the Hessian of a function of solution, such as the Mach number, will be a good addition to the code.
