Effective timestep for the current substep
real(kind=dp), public :: stage_dt

Time the current substep has advanced the solution from the start of the step, c_i*dt for RK stage i and dt for AB. Each substep starts from the divergence-free start-of-step field, so this is the timestep the pressure correction that follows the substep is scaled by.

Functions

public function nolds_of(time_intg) result(nolds)

Number of old-step blocks per variable that a time_intg_t keeps: k - 1 for ABk (nstep - 1) and k for RKk (nstage). Static, so that x3d2-memcheck can size the history blocks without allocating them.
