Hi,

I am working on a simulation tool for wind turbine blade fatigue testing.

The gif on this page is worth a thousand words...

I have written a beam element FEA code in MATLAB that allows a transient analysis to be performed. It works great, but in order to get the model to match up to physical test results I have to use a very high drag coefficient for the blade when simulating the damping that occurs due to air resistance. I have a colleague who is a CFD expert and he has agreed to do a bit of CFD analysis, however he is new to Ansys CFX. As he is working on this problem more or less in his spare time, I was wondering if anyone has any pointers for the analysis I've outlined below?

Aerofoil with 1m chord length moving up and down with simple harmonic motion. The frequency is 1Hz and the amplitude is 1m. The analysis is 2D.

I'm looking for help with time step size, and any settings that will get it working etc. Any help would be much appreciated!
