2011 SW Flow Sim Coefficient of Lift/Drag

Jason Chan Oct 19, 2012 11:50 PM

Hi All,

Does anyone know if Soldiworks 2011 is able to find the Lift and Drag coefficients? I can't find it under the 'goals' menu.

Regards,

Jason

yes. You need to set up an equation goal that take the force you want and divide it by q*A - take the equation and solve for the Cd of Cl.

  is q just the dynamic pressure - which can be taken from the goal dynamic pressure goal?

    or just calculate it and use the number in the equation goal. Its not like it changes or anything - it is a global flow parameter from the free stream. Since I just did this the other day here it is all layed out:
