Every load you calculate, the power output you predict, it all is calculated using tools that will have simplifications of the real world. It is always of vital importance to know what the validity of your code is, do you cross the boundaries of its validity using your latest design?

We can help you evaluate the software that you use and explain what possible short comings there are and perhaps provide you with suggestions on how to improve the chain of software you use. Using over 20 years of experience in the field of aeroelastic calculations using all kind of different tools for ever increasing wind turbine designs, we are very well aware of possible issues that arise from simplifications in different codes, from the approximations that are used and if this is relevant for your latest design or not.

To give an example, there are many codes that use only the linearised modes of the blades in the load calculations. This does not have to be a problem, but it can be a serious inaccuracy if the linearisation is performed about the undeformed state and your blade is large and rather flexible.  

So if you have any doubts about your results, or you see something weird in the results and are hoping it is not realistic, but not sure, we can help you and check if it is to be expected that the code you use does not perform well in your specific case or if the results are likely to be correct and perhaps the design needs changes. In that case we can advise you which property to change.
