PostProcess "0/uniform" data

nusivares · September 17, 2016, 12:47

Hi all,

I am struggling to find the information how to postprocess the uniform data into a CSV file on OpenFOAM. Essentially I have a transient analysis runs with the source term added as fvOptions into the momentum equation. This term is then saved into somthing similar to "0/uniform/momentumSourceProperties.gz"

Essentially I want to extract it against the time into a csv.

This proves fairly stressful and I am in a desperate need for help.

Hi Nusivaries,

Is the momentum source term also printed in the log file as the code runs? If so you can use Unix code similar to that found in the link below to extract both run time and the pressure gradient term.

That is how I have done it in the past!
