Basically I am comparing Blended Wing Body (BWB) aircraft to conventional aircraft (such as Boieng 737) and am expecting lift-to-drag ratios of the BWB’s to be higher than that of the conventional aircraft. I am also using ParaView to visualise the data and get lift-to-drag ratios.
I have created my own project in SimScale called ‘BWB testing no1’ (it is shared with support), and I have managed to get a good convergence plot with residual values down to 1E^-6. However, when I open the data in ParaView, my model has very rough edges and is not very similar to the original model - why is this? Could it be a problem with the mesh generation in SimScale?
Also, as you can see in the attachment (‘Paraview BWB’) in the top right corner, I am getting a lift value much smaller than the drag value, and the lift should really be higher than the drag. Why might this be and how I can fix it? I really need and appreciate any help as I do not have long to finish this. Thank you!
