 August 2, 2005, 01:55 Lift and Drag force #1 Dmitriy Guest   Posts: n/a I am working in ansys 9.0 and using flotran module to calculate pressure and velocity distrubition over 2D domain. There are an airfoil profile in domain. Calculations are done, but i need to know drag and lift forces. Does somebody know how to calculate it in ansys?

 September 18, 2005, 01:00 Re: Lift and Drag force #5 Mahesh Agarwal Guest   Posts: n/a Dear Freind, First you have to calculate total force nornal to aerofoil ( N ) then yu have to calculate total force paraller to aerofoil(P) then yu use formula force = 0.5*density*velocity*velocity*(area)*Cl this will give lift coefficient similarly yu can use for drag coefficient N=Lift P= Drag if yu have further dought then let me know regarding this matter
