Reference time step.
This is the time step value used in the case of a calculation run with a uniform and constant time step, i.e. idtvar =0 (restart calculation or not). It is the value used to initialize the time step in the case of an initial calculation run with a non-constant time step(idtvar=1 or 2). It is also the value used to initialise the time step in the case of a restart calculation in which the type of time step has been changed (for instance, idtvar=1 in the new calculation and idtvar = 0 or 2 in the previous calculation).
See Time step modification for examples.

integer(c_int), pointer, save ntcabs |
Current absolute time step number. In case of restart, this is equal to ntpabs + number of new iterations.
integer(c_int), pointer, save ntinit |
Number of time steps for initalization (for all steps between 0 and ntinit, pressure is re-set to 0 before prediction correction).
integer(c_int), pointer, save ntmabs |
integer(c_int), pointer, save ntpabs |
real(c_double), pointer, save ttcabs |
Current absolute time.
For the restart calculations, ttcabs takes into account the physical time of the previous calculations.
If the time step is uniform (idtvar = 0 or 1), ttcabs increases of dt (value of the time step) at each iteration. If the time step is non-uniform (idtvar=2), ttcabs increases of dtref at each time step.
ttcabs} is initialised and updated automatically by the code, its value is not to be modified by the user.
