Reports and PostProcessing options/features
hi,
I've been using BARAM for some basic external aircraft aerodynamics and have noticed a few things which may be useful or improved, or i could have missed if BARAM can already do this.
- full ForceCoeff output incl Cm_pitch, Cm_roll, Cm_yaw, useful when computing stability derivatives. i'm currently doing this post run in excel.
- Bin forces data along axis to get cumulative or non cumulative forces along a body, these can be plotted later.
- ability to postprocess these after completing a batch set of cases, for all cases which have been batch run, to speed up case run times.
- option to extract all the forces and coeffs from these .dat files and put into a single CSV file with a case name & angle for reporting and further analysis
also, Many thanks for creating BARAM GUI, it makes using openfoam much much easier and more useful.
Dear Ben watton,
Thank you for your various suggestions. It seems that the points you mentioned are necessary for external aerodynamics calculations. Since Baram is not a program specifically designed for external aerodynamics, there may be some inconveniences. We have already received a request regarding the first point and are currently reviewing it. As for the second point, I’m not entirely sure what you mean. If you could provide more details, I’ll look into it. I’ll also log the third and fourth points as development issues and review them.

hi, with regards to my second point. openfoam allows data to be 'binned' along a selected axis e.g. x axis. and forces recorded within each of those bins.
see below and example setup. the 'binData' section. i can do this post case run currently, but would be nice to add it in to a force/forcecoeff tab.
forces1
{
type forces;
libs ("libforces.so");
patches (wall);
p p;
U U;
rho rhoInf;
rhoInf 1;
cofR (0 0 0);
binData
{
nBin 20;
direction (1 0 0);
cumulative yes;
}
}
i have uploaded an example plots you can obtain from this data, i hope that makes sense.

Thank you for the detailed explanation. I understand what you mean. I will take this into account in our future development plans.
