Dear friends,

I was curious about the time varying loads on the helicopter blades in the forward flight. After reaching lots of books and documents, I came to know that some control (cyclic) is applied to take care of the dissymetry of lift in the forward flight. My question is, if the dissymetry of lift is eliminated by applying the cyclic control or by blade flapping (whatever), then why the load should vary with time for the 90 and 270 position of the blade? Can anybody explain this? Please let me know the justification. I am really curious about it. 

Hello everybody,

I am trying to run a cosimulation of fsi model with abaqus 6.12 in heat transfer step. But after running for 0.2 seconds, everything hangs or stops showing your computer is low on memory. Can anybody tell me why this happens? I have to run it for 50 seconds and I am trying it in the workstation computer of 32 GB RAM. Also, can anybody tell me how to make good mesh to teeth of a spur gear?

Thanks

Pratik
