I am using icoFoam to calculate a simple fluid, however I want to change the time step dynamically, e.g. first time step is: deltaT[1]=0.001, the next time step is deltaT[2]=0.003, the next is deltaT[3]=0.002, and so on.
i.e.
t0=0
t1=0+0.001=0.001
t2=0.001+0.003=0.004
t3=0.004+0.002=0.006

Maybe it is a wired problem, but in my program it seems that I need such kind of dynamic timestep, is it possible to program it in OpenFOAM? I didn't find any function like runTime.setTimeStep(DeltaT)...the only function I found is adjustDeltaT() but it is protected and after I read through the source, I found it is not doing what I want.

Thanks a lot!
