    Best CFD package for Aeroelasticity.

    I remembeeeeer !!!... I have the Demos of COMSOL at home... always looked at it as something for researchers more than a software for working with real world models. I've looked at it, seems it has a great potential. But it don't seem to manage big models. I'll look at it better and then I'll...

    Best CFD package for Aeroelasticity.

    Hi, I've been working with structures with Abaqus for 5 years, now I'm starting to do a research about wind generators blades and I need to work hard with fluid-structure interaction problems. As far as I know, the CFD codes usually work together with a structural solver to solve the...

    Impact Load on spindle

    Thanks very much Greg. I was supposing the contact will be the responsible of almost every energy loss. Since I dont have a lot of experience with that simulation I wanted to find someone who actually knows about that. I will let you know about the results. Thanks a lot for this help. Polaco

    Impact Load on spindle

    Thanks very much Greg,I understand your explanation. Note that I am not solving the dynamic response of the structure to a periodic excitation. I am using an explicit simulation with a length of 0.05 seg (the duration of the event). What would occur if the excitation bandwith was in the range...

    Impact Load on spindle

    Hi, I am trying to simulate an impact load on a truck spindle. My model contains the spindle, the knuckle,two bearings (modelled as solid) and the brake disc. BCs are: an acceleration pulse in the center of the wheel and fixed boundary condition applied to the knuckle. The maximum measured...
