I must admit that I'm wasn't optimistic going into this - but keeping an open mind, I did it anyway.





Is it helping? I can't say... I bet the shape is highly referenced to the shape of the vehicle.... I haven't checked to see if I have access to the journal, so I haven't read the paper yet...


So, I'm tired of not being able to compare these things any way but subjectively by visualization.... So I'm changing modes. For now, I'm going to continue with the 2D models - but now run them as 2D in floworks. I'm adding a total force goal and am going to record total force... Maybe, I'll add a cD equation in there (purely academic, but seems to be a good metric that is understood by many ).

I'll work on compiling a table of models and the corresponding forces (max, average and minimum).
