Hello everyone,
I’m performing aeroacoustics transient solver with local time step or two physical time. The process of the simulation is showed as following: 1)UEqn.H 2)pEqn.H (which is same as the pisoFoam and the two is controlled by larger time step T_flow) 3) aco.H : the aco.H reads some information from the flow field and doesn’t return results to the flow field. In this process, the time step of aco.H, I hope, is 10 times smaller of T_flow(T_aco = 0.1T_flow) and the value “10 times” is the fixed value that I can input. Therefore, my problems is how to implement it T_T and I have no clues on it. To be more detailed, how to perform time-control in OpenFOAM ? Thank you very much if you can give me a hand! |

Hey,
simply spoken:
Code:
if (runTime.value() % 10 == 0) { // Execute all from pisoFoam } acoustic.eqn; Cheers.
