Hello everyone,
today I come to you because I have a concern at the error calculation.
I have a Vortex flow Rankine. I have the theoretical values of the velocity field according to the coordinates of detected particles. I also have numeric values which I found through a MATLAB code so.
So I u_theo, v_theo, u_num and v_num (with U = u ex + v ey) and I would calculate the error.
So my concern is that I know about the formula but I can not confirm it and I also happen not to find on the internet ..
I know it looks something like this: error = SQRT (SUM (i) SUM (j) (U_num - U_theo / U_num) * 1 /nx * 1 / ny) but I'm not sure ..
So I'd need a hand on it.
I Thank You in advance, Regards.
