Comments on the final set of equations

ASPECT solves the equations given in the previous sections in essentially the form stated. In particular, the form given in (1) implies that the pressure \(p\) we compute is in fact the total pressure, i.e., the sum of hydrostatic pressure and dynamic pressure (however, see Static or dynamic pressure? for more information on this, as well as the extensive discussion of this issue in Kronbichler et al. [2012]). Consequently, it allows the direct use of this pressure when looking up pressure dependent material parameters.
