Can anybody explain my log file
I am using InterFoam for my case to track interface between air and a fluid. I have defined my time step as 0.00001 sec. But in the log file I could not find any where this time step. Could anyone please explain me the calculation process adopted by OpenFoam for solving my case. I am not goot at C++ coding and finding tough time to understand the ternminology. Please look at my log file below:

Hi,
you must disable the adjustTimeStep option in "system/controlDict": Code:
adjustTimeStep no; Martin |
All times are GMT -4. The time now is 08:27. |
