Hi all,
I am running a range of natural ventilation simulations. I have a handful of function objects and two surfaces files that I want to run on the final time/iteration of the simulation once my convergence criteria has been met. The problem I am having is that when the simulation converges some of my function objects and my two surface files are not getting updated with the results from the final simulation time. The probes and residual function objects are updated correctly at the end of the simulation but my four volFieldValue, FieldMinMax and surface files are not. Does anyone know if there is a method by which I can either get my simulation to run all my function objects at time of convergence or re-run them after the simulation has finished? The postProcessing folder is updated correctly with all my function objects and surface files values at the declared writeIntervals in the controlDict. Ideally, I want to find a way for the simulation to automatically update the postProcessing folder at the end of the simulation instead of me having to manually change the writeInterval when the simulation gets close to converging. I have looked into the postProcess tool but when I use the -list command their is no volFieldValue in the list of function objects. So I am not sure if that function object is available for use with the postProcess tool. I am using OpenFOAM 8 on Ubuntu 18.04.2. I am running buoyantSimpleFoam in parallel on 6 processors. My simulations are converging correctly and the reconstruct process appears to be working as intended. Thank you in advance for any support you can provide me. Kind regards, Ben My controlDict: Code:
