Setting Description Range of panel’s indices used for pressure calculation X coordinate’s range used for pressure calculation X component of pressure taken into account for pitching moment calculation Calculation metod (0-8) Averaging of local coordinate system The values are the numbers of the first and the last panel which will be taken into account for pressure computations. X coordinate’s range used for pressure calculation (global aerodynamic coefficients). X component of pressure taken into account for pitching moment calculation. Computation method selection: 0 – average from two out four of described below methods, 1 – collocation method – with polynomial: φ(x,y)=Ax 2 y 2 +Bx 2 y+Cxy 2 +Dxy+Ex 2 +Fy 2 +Gx+Hy+I, 2 – collocation method (omitting point on current panel) – with polynomial: φ(x,y)=Bx 2 y+Cxy 2 +Dxy+Ex 2 +Fy 2 +Gx+Hy+I, 3 – approximation with polynomial: φ(x,y)=Bx 2 y+Cxy 2 +Dxy+Ex 2 +Fy 2 +Gx+Hy+I, 4 – approximation with polynomial: φ(x,y)=Dxy+Ex 2 +Fy 2 +Gx+Hy+I, 5 – method 1, 2 i 3, 6 – method 1, 2 i 4, 7 – method 1, 3 i 4, 8 – (default) method 2, 3 i 4. Averaging of local coordinate system to eliminate errors during potential differentiation. 40
