please help... urgent ... Unsteady Flow
 
Hi, just one simple question. I have an unsteady velocity starting from t=0s. If I choose a time step of 0.1s and use fluent to compute and autosave every time step, is the first solution based on t=0s or t=0.1s? thanks a million.

Fluent updates the solution by increasing one step for the first iteration. Therefore t=0.1s

The saved solution is always calculated ad the time you save (or autosave) the .dat file.
