5 months ago $p^*$ in the Oasisx tutorial is $p^{n-3/2}$, i.e. the pressure from the last time step. In oasisx I used the notation $u^n$, $p^{n-1/2}$ to denote the solutions at a given time step, while in the tutorial I use a slightly different indexing (add 1 to n everywhere).
I don't see why the equation
containts $p^{n-1/2}$.
In the analogous equation for the tentative velocity $u^\ast$ here, see
,
$p^\ast$ enters the equation, not $p^{n-1/2}$.
