I calculated the forces/moments (lift/drag coefficients) for an aircraft according to a very good tutorial provided here. But I am still unsure about the results or if I still need to do a grid depency test.
Does anyone know of calibration models with wind tunnel results that can be used to calibrate/cross-check the CFD results?
Sorry for the delay in my response, do you mind sharing your project? In general a grid dependency study is recommended, would love to see what results you expect and what you got out of your simulation
