| Summary | 0003758: Variable time step not working in reactingFoam when engineTime is used | ||||
| Description | I am trying to simulate the combustion of methane in an internal combustion engine, using the reactingFoam solver. The kinetic mechanism I am trying is GRI. You can find uploaded two case folders in which the only difference is that in one of the two cases (reactingFoam_VTS) the "adjustTimeStep" option is enabled. In the two folder cases, you can find the log file where I registered the first time steps calulations. In the one with the adjustTimeStep option enabled, the input parameters are correctly read, but the first time step which is calculated is 71 CAD (starting from -145), and then, after 71, smaller time steps are computed. Note: I noticed that the variable time step works as expected in the kivaTest tutorial. | ||||
| Steps To Reproduce | Download the case folders and run reactingFoam | ||||

The content of the -145/uniform/time file is out of date and inconsistent, I suggest you delete the -145/uniform directory. Also given that you are adjusting the time step it would make sense to use writeControl adjustableRunTime; |

It works fine now! Thank you very much, the folder uniform never gave me this problem, thank you! |
