Hello
I have a situation such that there are 2 time scales (a,b) available other than the one based on CFL condition .

I want to do time-stepping based on

delta_t=min(a,b, t_based_on_Co).
------------------------------------------------------------------------
(If a, b are constants I could do it by editing setDeltaT.H as


runTime.setDeltaT
(
min
(
deltaTFact*runTime.deltaTValue(),
maxDeltaT,
a,
b
)
);
---------------------------------------------------------------------------
But what if I have dynamically calculated a and b.
Could someone suggest me how I could do this

I make the option directly in the solver, and compile with wmake again.
