hi dear foamer
i simulated stephan problem ( phase Change ) with open Foam a modified version of interFoam, now im going to compare the result with analytical solution, unfortunately time is making me messed up! what is the time ? it seems stupid but the question is?
1) is this time real time ( physical time on second ) ?
2) if yes, so could some one tell me whats the difference between timeStep,adjustableRunTime and runTime
im using an implicit method to solve alpha1 equation in interFoam.

timeStep：write data every N time steps, where N is defined in writeInterval;
runTime: write data every t seconds, t is the simulated time which is defined in writeInterval;
adjustableRunTime: write data every t seconds, used in cases with automatic time step adjustment, it will change the time step to conincide with the writeInterval;
Basically, the three methods mentioned above are simulated flow time.
In caomparison, cpuTime and clockTime is not flowtime, it's either related to the time in windows clock, or in CPU time.
If I'm wrong, please let me~
