    Wing downwash calculcation

    Hi man, that is a so called "singular integral". See http://en.wikipedia.org/wiki/Singular_integral. There are specific numerical methods for solving this kind of problem.

    ERROR NASTRAN CENTRIFGAL FORCES

    Hi dudes! I need to study a rotating flapping wing subjected to angular velocity depending on time with Nastran. I found that Nastran does not calculate correctly the centrifugal forces and deformations in the case of the SOL Transient Dynamic/Time History, while the forces and deformations...

    Nx Nastran Angular Velocity

    Hi, thank you for replying. I tried to give separate load cases for each direction but I can do that only a static analisis, The SOLUTION 601, which is the Advanced Nonlinear Transient, can analyze only one bodyload per time. Anyother tip? appreciate it!

    Nx Nastran Angular Velocity

    Hi dudes, I'm studying micro flapping vehicles. I need to evaluate the inertial forces due to the angular velocity of the wing during a cycle. The angular velocity varies in strength and in direction I found the way for setting on NX Nastran an angular velocity with varying strength but I did...
