    How to get Clalpha and Cmalpha?

    I wanted to know if there is a way to get those coefficient in sol146 without using matrix QHHL. Thanks!

    Problem using sol 146

    Hi! I'm using MSC.Nastran and I have problems to get results using sol 146. I have been asked to get the pression and lift distribution on my model using the doublet-lattice method for a given Mach number and reduced frequency. I've had no problems doing the sol 144 but the reduced frequency...

    Mass per unit length

    Thanks for the answer. I have done that by defining 1D elements using the property CBAR (we are free to use the elements we want). I have used a bar orientation that is perpendicular with the union I want to make and a ''random'' area. To not waste too much time I've only tried that on a part of...

    Mass per unit length

    Thanks for the answer. I am modeling a wing but with a simple geometry. The problem is that, I don't have the density of the material, only the mass per unit length (it's for an essay). So I don't know how to apply it

    Mass per unit length

    I have created a 3D geometry but I only have the ''mass per unit length''. How can I apply it in order to study its normal modes? I have tried everything but I can't find it Thanks!
