Effect of tower tilting #50

Open sanowershamim opened 3 years ago

sanowershamim commented 3 years ago

I work with a floating vertical axis wind turbine. There, I need to quantify the effects of tower tilting on turbine performance. I think there exists two ways for this purpose. 1. changing the geometry 2. changing inflow angle. However, I am still uncertain how to do this in CACTUS?

Hi all, I'm also interesting in this topic, and I'd like to try and upgrade Cactus to achieve static or dynamic fore-aft tilting. Any information on what's the best approach for that would be great. I'm guessing a secondary subroutine along the lines of RotateBlade would be suitable, any opinion ? thanks

Hi Everyone, I am new to coding and doing my best to learn it. I am having issues understanding the Cactus geometry file. I want to simulate a straight-bladed rotor with three blades (Like RM2 tow-tank Experiment Sandia Lab). I don´t know how to calculate the blade unit tangent vectors for my simple geometry to modify the cactus geometry file. I would appreciate it if you can provide any document to understand this geometry file. So far I have the Cactus and the Cactus development Manual Only. Thank you. @benoitpaillard @sanowershamim
